After the staging installation, we replace a number of paths in libtool
.la files so that those paths point to STAGING_DIR instead of a location
in the build machine.
However, we replace only paths that start with /usr. And it turns out
that the linux-pam package is configured with --libdir=/lib (linux-pam
seems to always be installed in /lib rather than /usr/lib).
Due to this, libpam.la contains the following line:
libdir='/lib'
When building a configuration that has:
- BR2_ROOTFS_MERGED_USR=y
- BR2_PACKAGE_LINUX_PAM=y
- BR2_PACKAGE_POLKIT=y
on a system that has its system-wide PAM library installed in /lib,
the build fails with:
/lib/libpam.so: file not recognized: File format not recognized
For some reason, libtool searches only in STAGING_DIR/usr/lib, but
when BR2_ROOTFS_MERGED_USR=y, STAGING_DIR/lib points to
STAGING_DIR/usr/lib, so libtool finds libpam.la. And this libpam.la
contains a bogus libdir='/lib' path. libtool then goes on, finds
/lib/libpam.so, and links with it, causing the build failure.
By doing the proper replacement of libdir='/lib', we have a correct
libpam.la, and solve the build issue.
There is no autobuilder failure associated to this issue, as it
requires /lib/libpam.so to exist. This is the case on ArchLinux, on
which Xogium reported the issue, which can also be reproduced in an
ArchLinux container.

In commit 0e2be4db8a
("package/pkg-generic: make file list logic parallel build
compatible"), the logic to create the list of files installed by a
particular package was significantly reworked to be compatible with
top-level parallel build.
Before this commit, there was only a after-install step of listing the
files in HOST_DIR/TARGET_DIR/STAGING_DIR. But after this commit, we
now have a before-install logic and an after-install logic.
It turns out that when the before-install logic is called for the very
first host package, $(HOST_DIR) doesn't exist yet, and therefore the
cd $(2) fails, with an error message:
/bin/sh: line 0: cd: /home/thomas/buildroot/output/host: No such file or directory
In fact, $(HOST_DIR), $(STAGING_DIR), $(TARGET_DIR) and
$(BINARIES_DIR) are created by the make rules for host installation,
staging installation, target installation and images installation, but
*after* calling the step_start hooks.
So, we simply fix this problem by creating the directories *before*
calling the step_start hooks.

The current solution used to collect the list of files installed by
packages does not work for top-level parallel build. Indeed, we rely
on a file created after the installation of the previous package to
build the list of files installed by the current package.
This works well when packages are built sequentially, but badly fails
when using top-level parallel build.
More specifically, top-level parallel build can fail with:
comm: /home/thomas/buildroot/output/build/.files-list-host.new: No such file or directory
Because that file has been removed concurrently by the build process
of another package.
This commit reworks the logic in a very straight-forward way. Before
the installation of each package, we store the list of files that are
already installed and store it in the package build directory. After
the installation of each package, we store again that list of files,
calculate the difference with the before file, and store that as the
list of files installed by that package, still in the package build
directory.
At the end of the build, in target-finalize we collect all the
collected information into the global package file lists, that
continue to be installed in the same location as before, with the same
name.
There are however some differences:
(1) The files are no longer ordered in build order, but by alphabetic
ordering of packages. Indeed, "build order" no longer makes any
sense in the context of top-level parallel build.
(2) Some files which were incorrectly tracked are no longer
tracked. For example, the toolchain package is a target package,
but it installs files in $(HOST_DIR). In the previous logic, the
files installed by the toolchain package in $(HOST_DIR) were
incorrectly affected to the next host package that was installed
after the toolchain package. With our new logic, those files are
no longer tracked at all. To fix this, we would have to change
the logic to scan HOST_DIR/TARGET_DIR/STAGING_DIR for all
installation steps, not just for the install-host, install-target
and install-staging steps respecitively. But the result was
already incorrect anyway, and therefore this should be fixed
separately.
Note that the check_bin_arch hook needs to be adjusted: it was using
the global package-file-list.txt file, but this file is now created
only at the very end of the build. So instead, we use the current
package .file-list.txt file to know which packages have been installed
by the current package in $(TARGET_DIR).

The package instrumentation step 'step_pkg_size' is populating the files:
output/build/packages-file-list.txt
output/build/packages-file-list-staging.txt
output/build/packages-file-list-host.txt
by comparing the list of files before and after installation of a package,
with some clever tricks to detect changes to existing files etc.
As an optimization, instead of gathering this list before and after each
package, where the 'after-state' of one package is the same as the
'before-state' of the next package, only the 'after-state' is used and
is shared between packages.
This works fine, except at the end of the build, as explained next.
In the target-finalize step, many files will be touched. For example, files
like /etc/hosts, /etc/os-release, but also all object files that are
stripped, and all files touched by post-build scripts or created by rootfs
overlays. This means that the 'after-state' of the last package does not
reflect the actual situation after target-finalize is run.
For a single complete build this poses no problem. But, if one incrementally
rebuilds a package after the initial build, e.g. with 'make foo-rebuild',
then all changes that happened in target-finalize at the end of the initial
build (the 'after-state' of the last package built) will be detected as
changes caused by the rebuild of package foo. As a result, all these files
will incorrectly be treated as 'owned' by package foo.
Correct this situation by capturing a new state at the end of
target-finalize, so that the 'before-state' of an incremental build will be
correct.
Note: the reasoning above talks about packages-file-list.txt and
target-finalize, but also applies to
packages-file-list-staging.txt/staging-finalize and
packages-file-list-host.txt/host-finalize.

For now, the extractor dependencies were only calculated for
<pkg>_SOURCE, so if the package manually downloads another file using
<pkg>_EXTRA_DOWNLOADS and then extracts it with $(call
suitable-extractor), we are missing the corresponding dependency on
the appropriate extracting tool.
Since the vast majority of <pkg>_EXTRA_DOWNLOADS are compressed files
that will be uncompressed at build time, it makes sense to derive the
corresponding extractor dependencies directly in the common package
infrastructure, rather than having each and every package using
<pkg>_EXTRA_DOWNLOADS making this effort.
On a system without xzcat, before this patch:
$ make printvars VARS=HOST_GETTEXT_TINY_EXTRACT_DEPENDENCIES
HOST_GETTEXT_TINY_EXTRACT_DEPENDENCIES=host-tar
After this patch:
$ make printvars VARS=HOST_GETTEXT_TINY_EXTRACT_DEPENDENCIES
HOST_GETTEXT_TINY_EXTRACT_DEPENDENCIES=host-tar host-xz
This commit most notably fixes the build of host-gettext-tiny on
systems without xzcat, and with per-package support enabled. Indeed,
the main _SOURCE for gettext-tiny is a .gz file, but it has a .xz file
in its _EXTRA_DOWNLOADS, which is then extracted. Except that xzcat
being missing from the dependencies, it is not built.

Commit c4e6d5c8be ("core: implement

to match $(PER_PACKAGE_DIR)/<something>/, and due to this, the regexp
was never matched.
The + sign in [^/]+ which was suggested by Yann E. Morin during the
review of the per-package patch series (instead of [^/]*) needs to be
escaped to be taken into account correctly. Without this, the regexp
doesn't match, and the replacement is not done, causing:
(1) For the libtool fixup in pkg-generic.mk, the lack of replacement
causes libtool .la files to not be tweaked as expected, which it
turn causes build failures reported by the autobuilder.
(2) For the fix-rpath, the RPATH of host binaries in the SDK were not
correct.
Interestingly, we have the same regexp in
support/scripts/check-host-rpath, but here the + sign does not need to
be escaped.

When BR2_PACKAGE_PYTHON{,3}_PYC_ONLY=y, we force remove all .py files
from the system, as they have all been byte-compiled into their .pyc
variants.
However, it turns out that some packages (e.g: OpenCV) do some funky
things with a few .py files: they pass them through Python's
execfile() facility, which only works with .py files and not .pyc
files. It is used by OpenCV for example to read two small
configuration files.
In order to support such use cases, this commit introduces a very
simple mechanism by which packages can exclude some path patterns from
the .py removal: a per-package <pkg>_KEEP_PY_FILES variable that is
collected into a global PYTHON_KEEP_PY_FILES variable, then used by
the python/python3 target-finalize hooks.
This variable is intentionally not documented, this is really a hack
that we ideally would like to see go away, and we'd rather not see its
usage spread too much.
This is necessary to be able to fix bug #12171.

Libtool .la files unfortunately contain a number of absolute paths,

package A, .la files may contain absolute paths referring to
directories in package B per-package sysroot. This causes some -L
flags referring to other sysroot from being added, which doesn't work

This commit implements the core of the move to per-package SDK and
target directories. The main idea is that instead of having a global
output/host and output/target in which all packages install files, we
switch to per-package host and target directories, that only contain
their explicit dependencies.
There are two main benefits:
- Packages will now see only the dependencies they explicitly list in
their <pkg>_DEPENDENCIES variable, and the recursive dependencies
thereof.
- We can support top-level parallel build properly, because a package
only "sees" its own host directory and target directory, isolated
from the build of other packages that can happen in parallel.
It works as follows:
- A new output/per-package/ directory is created, which will contain
one sub-directory per package, and inside it, a "host" directory
and a "target" directory:
output/per-package/busybox/target
output/per-package/busybox/host
output/per-package/host-fakeroot/target
output/per-package/host-fakeroot/host
This output/per-package/ directory is PER_PACKAGE_DIR.
- The global TARGET_DIR and HOST_DIR variable now automatically point
to the per-package directory when PKG is defined. So whenever a
package references $(HOST_DIR) or $(TARGET_DIR) in its build
process, it effectively references the per-package host/target
directories. Note that STAGING_DIR is a sub-dir of HOST_DIR, so it
is handled as well.
- Of course, packages have dependencies, so those dependencies must
be installed in the per-package host and target directories. To do
so, we simply rsync (using hard links to save space and time) the
host and target directories of the direct dependencies of the
package to the current package host and target directories.
We only need to take care of direct dependencies (and not
recursively all dependencies), because we accumulate into those
per-package host and target directories the files installed by the
dependencies. Note that this only works because we make the
assumption that one package does *not* overwrite files installed by
another package.
This is done for "extract dependencies" at the beginning of the
extract step, and for "normal dependencies" at the beginning of the
configure step.
This is basically enough to make per-package SDK and target work. The
only gotcha is that at the end of the build, output/target and
output/host are empty, which means that:
- The filesystem image creation code cannot work.
- We don't have a SDK to build code outside of Buildroot.
In order to fix this, this commit extends the target-finalize step so
that it starts by populating output/target and output/host by
rsync-ing into them the target and host directories of all packages
listed in the $(PACKAGES) variable. It is necessary to do this
sequentially in the target-finalize step and not in each
package. Doing it in package installation means that it can be done in
parallel. In that case, there is a chance that two rsyncs are creating
the same hardlink or directory at the same time, which makes one of
them fail.
This change to per-package directories has an impact on the RPATH
built into the host binaries, as those RPATH now point to various
per-package host directories, and no longer to the global host
directory. We do not try to rewrite such RPATHs during the build as
having such RPATHs is perfectly fine, but we still need to handle two
fallouts from this change:
- The check-host-rpath script, which verifies at the end of each
package installation that it has the appropriate RPATH, is modified
to understand that a RPATH to $(PER_PACKAGE_DIR)/<pkg>/host/lib is
a correct RPAT.
- The fix-rpath script, which mungles the RPATH mainly for the SDK
preparation, is modified to rewrite the RPATH to not point to
per-package directories. Indeed the patchelf --make-rpath-relative
call only works if the RPATH points to the ROOTDIR passed as
argument, and this ROOTDIR is the global host directory. Rewriting
the RPATH to not point to per-package host directories prior to
this is an easy solution to this issue.

When a package specifies extra downloads, it has the option to only name
the basename of the extra download, in which case that extra download
will be retrieved from the same location the main download is retrieved
from.
In that case, if the extra download contains a '+', it would confuse the
dl-wrapper, which believes the LHS of the '+' is the site method, and
the RHS the actual URI, and so the dl-wrapper mangles and damages the
URI when fetching such extra downloads, like that happens with android
tools, where the proper URI and mangled URIs of the extra download are,
respectively:
https://launchpad.net/ubuntu/+archive/primary/+files/android-tools_4.2.2+git20130218-3ubuntu41.debian.tar.gzhttp://archive/primary/+files/android-tools_4.2.2+git20130218-3ubuntu41.debian.tar.gz
We fix that by always propagating the site method to extra downloads,
but only when they are specified as relative to the main download URI.
For the extra downloads that specify a full URI, it is not systematic
that it is the same site method. For example, a main download could be a
git clone, but an extra download a pure http download; in that case we
can't replicate the site method for extra downloads, so they'll have to
take appropriate care to specify the required method and encoding if
needed.

This really departs from the simplicity and consistency of using the

This is because the append-assignment operator surreptiously
introduces a space between the original value and the appended one. But

not actually create a file. Furthermore, to avoid the "Nothing to be

nothing.

Currently, when we tweak the .la files, we do so unconditionally on all
.la files, even those we already fixed in a previous run.
This has the nasty side effect that each .la file will be reported as
being touched by all packages that are installed after the package that
actually installed said .la file.
Since we can't easily know what files were installed by a package (that
is an instrumentation hook, and comes after the mangling), we use a
trick (like is done in libtool?): we do mangle all files, each into a
temporary location; if the result is identical to the input, we remove
the temporary, while if the result differs from the output, we move
the temporary to replace the input.

Currently, when we need to build the full dependency graph, we call make
to show the list of packages (make show-targets), and then call it again
and again iteratively while it returns new packages.
Since calling make will parse the whole set of our Makefiles, this takes
quite a bit of time (~4s each here), and the total can get pretty long.
However, make being make, already builds the whole dependency tree
information, so we can just ask for it.
Add a new top-level rule 'show-dependency-tree' that displays the whole
set of dependencies for all packages. For each package, its name, type
and version is displayed, then all the direct, first-level dependencies
are dumped. We choose a format that is not unlike the dot-graph format,
because it is both easy to read as a human, and easy to parse as a
machine:
foo: target 1.2.3
foo -> bar host-meh
bar: target virtual
bar -> buz
buz: target 2.3.4
buz ->
host-meh: host virtual
host-meh -> host-bleark
host-bleark: host 3.4.5
host-bleark ->
rootfs-meh: host
rootfs-meh -> host-bleark
To be noted: rootfs are currently reported as if they were 'host'
packages, to stay aligned with how graph-depends currently treats them.
Ideally, graph-depends could be enhanced to recognise them separately,
but that is another story.
For just plain defconfig, which is about the smallest config we can have
with an internal toolchain, we already have a seven-fold improvement
(with the graph-depends rule modified to not run the pdf generation, to
be able to just compare the tree generation):
$ time make graph-depends
real 0m27.344s
$ time make show-dependency-tree
real 0m3.848s
>From defconfig, C++, wchar, locales, ssp, and allyespackageconfig,
tweaked for even more packages (qt5 not qt4, luajit to avoid multi
providers, etc...), the timings are (graph-depends still modified to
not generate the pdf):
$ time make graph-depends
real 1m56.459s
$ time make show-dependency-tree
real 0m5.748s
There. I don't think those numbers need any explanation whatsoever;
they do speak on their own. OK, for maths sake, the ratio is about
twenty-fold. So, "yeah", I guess... ;-)

Calling to the graph-depends script is very costly, as it calls back to
'make' a lot of time.
It turns out that we already have the list of recursive dependencies, so
we can just print that.
As for the recursive reverse dependencies, we use the same memoisation
technique to cut-down on the expansion cost, which would otherwise be on
the order of 𝑶(𝑛²) (with 𝑛 enabled packages).
>From a defconfig, modified to use glibc, C++, wchar, locales, ssp, and
allyespackageconfig (tweaked to avoid multi providers, etc...), the
timings for X-show-recursive-rdepends are:
before after speedup #rdeps
libnss 0m22.932s 0m5.775s 3.97x 3
qt5base 0m41.176s 0m5.781s 7.12x 67
libjpeg 0m56.185s 0m5.749s 9.71x 228

libpng 0m53.577s 0m5.760s 9.30x 303
sqlite 1m15.222s 0m5.807s 12.95x 801
libopenssl 1m25.471s 0m5.844s 14.63x 931
readline 1m13.805s 0m5.775s 12.78x 958
libzlib 1m11.807s 0m5.820s 12.34x 1039
toolchain 1m23.712s 0m6.080s 13.77x 2107
skeleton 1m27.839s 0m6.293s 13.96x 2111 (+1)
host-skeleton 1m27.405s 0m6.350s 13.76x 2172 (+2)
- speedup: ratio before/after
- #rdeps: number of recursive reverse dependencies, with the extra
dependencies returned with this patch, see below for the
reason.
So, for a low-level package with a lot of reverse dependencies, like
libzlibz, libopenssl or readline are, the timings are already very much
in favour of the change. This is less impressive with packages that
have few dependencies (libnss), but still much faster.
Also, remember that the config tested has as much packages enabled as
possible, so is in itself a degenerate case. With simpler and more
realistic configurations, the gains would probably be a bit lower than
reported above, but various tests still report good improvements
overall (note: coming up with a 'realistic' configuration is pretty
hard, as everyone and their dog have their notion of what is realistic
in their context, so nothing displayed here; timings are left as an
exercise for the interested parties to report aggravation in their
cases should they notice some regression).
Note that, more recursive reverse dependencies may be displayed now,
since we do not apply the exceptions applied in graph-depends. For
example, host-skeleton gains two new recursive reverse dependencies:
skeleton and toolchain, which are both exceptions in graph-depends.
As for direct (not reverse) dependencies: the gain is not as fantastic
as for reverse ones, but it is still noticeable, especially thanks to
a21212fb7c (package/pkg-generic: speed up RECURSIVE_FINAL_DEPENDENCIES);
just a few examples for %-show-recursive-depends:
before after speedup #deps
libzlib 0m46.864s 0m5.902s 7.94x 17
qt5base 0m57.590s 0m5.848s 9.85x 190
sqlite 0m46.601s 0m5.816s 8.01x 24
Basically, displaying recursive dependencies, direct or reverse, is
almost a constant now: it only slightly varies by about 10% depending
on the complexity of the dependency chain, with the parsing of the
Makefiles still accounting for the large majority of the time.
(PS. Thanks to Joseph for suggesting a list of interesting packages
to test, and thanks to Trent for his example of memoisation!)

Evaluating all the <PKG>_RECURSIVE_FINAL_DEPENDENCIES variables
(abbreviated RFD hereafter) ends up being quite slow. Enough, on a
reasonable modern workstation, to increase the time it takes to run
"make printvars" from 13 seconds in 2018.02 to 371 seconds in 2019.02.
This patch improves this by using dynamic programming to speed the
evaluation of RFD, reducing the before mentioned printvars time to about
14.6 seconds.
The evaluation of PKG1_RFD requires recursively evaluating each of
PKG1's dependencies' RFDs, then their dependencies' RFDs, and so on.
The same is done for PKG2_RFD. But it's likely that many of the
dependencies of PKG2 are the same as PKG1. And when we consider all
packages, the dependencies are re-computed many thousands of times.
To avoid this re-computation we memoize, or save, the computed value of
each RFD variable when it found the first time. Subsequent evaluations
re-use the memoized value.
Surprisingly, this ends up being not all the hard to implement in make.
The basic construct is this:
VAR = $(if !defined(VAR__X),$(eval VAR__X := value))$(VAR__X)
The first time VAR is evaluated VAR__X will not be defined, and code to
set VAR__X to the computed value is eval'd. Then the now defined value
of VAR__X is returned. Subsequent evaluations can just return VAR__X.
It is important to note that VAR is defined with '=', as not enough
information (namely, all packages' dependencies) is know when it is
parsed to find the correct value. VAR will be evaluated each time it is
used. But VAR__X is defined with ":=", so that it is evaluated once
when defined, and not each time it is used.

In commit 7fb6e78254 (core/instrumentation: shave minutes off the
build time), the built stampfile is used as a reference to detect files
installed by a package.
However, packages may install files keeping their mtime intact, and we
end up not detecting this. For example, the internal skeleton package
will install (e.g.) /etc/passwd with an mtime of when the file was
created in $(TOP_DIR), which could be the time the git repository was
checked out; that mtime is always older than the build stamp file, so
files installed by the skeleton package are never accounted for to that
package, or to any other package for that matters.
We switch to an alternate solution, which consists of storing some extra
metadata per file, so that we can more reasily detect modifications to
the files. Then we compare the state before the package is installed (by
reusing the existing list) and after the package is installed, compare
that to list any new file or modified files (in reality, ignoring
untouched and removed files). Finally, we store the file->package
association in the global list and store the new stat list as the global
list.
The format used for the .stat file is:
mtime:inode:perms:filetype:size,filename

In case a config script is called from a relative path, the $(dirname
$0) would return a relative path too.
Those paths are usually parts of includes or libraries search
directories, and the packagfes buildsystems may chdir() anywhere, and
thus the relative path will no longer be valid. For example:
$ ./host/powerpc-buildroot-linux-uclibc/sysroot/usr/bin/net-snmp-config --cflags
[...] -I./host/powerpc-buildroot-linux-uclibc/sysroot/usr/bin/../../.././bin/../powerpc-buildroot-linux-uclibc/sysroot/usr/include/libnl3 [...]

This commit adjusts the logic in pkg-generic.mk that tweaks the
*-config shell scripts installed by various libraries to make it
compatible with per-package directories.
This requires two fixes:
- replacing $(STAGING_DIR) with a relative path from the config script
to the staging directory, rather than using an absolute path of the
staging directory.
Without this, a *-config script provided by package A, but called
from package B per-package directory will return paths from package A
per-package directory:
$ ./output/per-package/mcrypt/host/usr/<tuple>/sysroot/usr/bin/libmcrypt-config --libs
-L..../output/per-package/libmcrypt/host/usr/<tuple>/sysroot/usr/lib/
The libmcrypt-config script is installed by the libmcrypt package,
and mcrypt is a package that depends on libmcrypt. When we call the
libmcrypt-config script from the mcrypt per-package directory, it
returns a -L flag that points to the libmcrypt per-package
directory.
One might say: but this is OK, since the sysroot of the libmcrypt
per-package directory also contains the libmcrypt library. This is
true, but we encounter a more subtle issue: because -L paths are
considered before standard paths, ld ends up finding libc.so in the
libmcrypt per-package directory. This libc.so file is a linker
script that looks like this:
GROUP ( /lib/libc.so.6 /usr/lib/libc_nonshared.a AS_NEEDED ( /lib/ld-linux.so.3 ) )
Normally, thanks to ld sysroot awareness, /lib/libc.so.6 in this
script is re-interpreted according to the sysroot. But in this
case, the library is *outside* the compiler sysroot. Remember: we
are using the compiler/linker from the "mcrypt" per-package
directory, but we found "libc.so.6" in the "libmcrypt" per-package
directory.
This causes the linker to really use the /lib/libc.so.6 from the
host machine, obvisouly leading to a build failure such as:
output/per-package/libgcrypt/host/opt/ext-toolchain/bin/../lib/gcc/nios2-linux-gnu/7.3.1/../../../../nios2-linux-gnu/bin/ld: cannot find /lib/libc.so.6
output/per-package/libgcrypt/host/opt/ext-toolchain/bin/../lib/gcc/nios2-linux-gnu/7.3.1/../../../../nios2-linux-gnu/bin/ld: cannot find /usr/lib/libc_nonshared.a
output/per-package/libgcrypt/host/opt/ext-toolchain/bin/../lib/gcc/nios2-linux-gnu/7.3.1/../../../../nios2-linux-gnu/bin/ld: cannot find /lib/ld-linux-nios2.so.1
- Some *-config scripts, such as the apr-1-config script, contain
references to host tools:
CC=".../output/per-package/apr/hosr/bin/arm-linux-gcc"
CCP=".../output/per-package/apr/hosr/bin/arm-linux-cpp"
We also want to replace those with proper relative paths. To
achieve this, we need to also replace $(HOST_DIR) with a relative
path. Since $(STAGING_DIR) is inside $(HOST_DIR), the first
replacement of $(STAGING_DIR) by @STAGING_DIR@ is no longer needed:
replacing $(HOST_DIR) by @HOST_DIR@ is sufficient. We still need to
replace @STAGING_DIR@ by the proper path though, as we introduce
@STAGING_DIR@ references in exec_prefix and prefix variables, as
well as -I and -L flags.

In the current code, the creation of the main output directories
(BUILD_DIR, STAGING_DIR, HOST_DIR, TARGET_DIR, etc.) is done by a
global "dirs" target. While this works fine in the current situation,
it doesn't work well in a context where per-package host and target
directories are used.
For example, with the current code and per-package host directories,
the output/staging symbolic link ends up being created as a link to
the per-package package sysroot directory of the first package being
built, instead of the global sysroot.
This commit reworks the creation of those directories by having the
package/pkg-generic.mk code ensure that the build directory, target
directory, host directory, staging directory and binaries directory
exist before they are needed.
Two new targets, host-finalize and staging-finalize are added in the
main Makefile to create the compatibility symlinks for host and
staging directories. They will be extended later with additional logic
for per-package directories.
Thanks to those changes, the global "dirs" target is entirely removed.

Recently, some hash mismatch have been reported, both by users as well
as autobuilder failures, about tarballs generated from git repositories.
This turned out to be caused by users having the 'gzip' command somehow
aliased to 'pigz' (which stand for: parallel implementation of gzip,
which takes advantage of multi-processor system to parallelise the
compression).
Unfortunately, the output of pigz-compressed archives differ from that
of gzip (even though they *are* valid gzip-compressed streams).
Add a dependency check that ensures that gzip is not pigz. If that is
the case, define a conditional dependency to host-gzip, that is used as
a download dependency for packages that will generate compressed files,
i.e. cvs, git, and svn.

When a package has a version selection (e.g. Qt5), the licensing terms
may be different across versions, but lie in similarly named files (e.g.
'LICENSE').
However, when we check a file, all the hashes for it must match. So, we
can't have the hashes for two different content of the same file. We
overcame that limitation in the legal-license-file macro, which checks
whether a package has a .hash file in a versioned subdir.
For consistency, we would like to also store the source hashes in that
per-version subdir.
Rather than reconstruct the path to the hash file everywhere we need it,
add a variable that points to it.
Existing users will be converted over in followup patches.
Note: the check for a missing hash file is done in the check-hash helper
script, so this variable must always yield a filename, even of a missing
file, thus we do not use $(wildcard...) to resolve the hash file path;
we use $(wildcard...) only to check if the versioned .hash file exists.

Currently, the timestamps that we keep in build-time.log use a
second-level precision. However, as we are going to introduce a new
type of graph to draw the time line of a build, this precision is
going to be insufficient, as a number of steps are so short that they
are not even one second long, and generally the rounding to the second
gives a not so great looking graph.
Therefore, we add to the timestamps the nanoseconds using the %N date
specifier. A milli-second precision would have been sufficient, but %N
is all what date(1) provides at the sub-second level.
Since this is changing the format of the build-time.log file, this
commit adjusts the support/scripts/graph-build-time script
accordingly, to account for the floating point numbers that we have as
timestamps.
