libcap builds an incorrect libcap.pc because libdir is pulled from the
host os:
ifndef lib
lib=$(shell ldd /usr/bin/ld|egrep "ld-linux|ld.so"|cut -d/ -f2)
endif
Fix this error by passing lib=lib and prefix in
{HOST_LIBCAP,LIBCAP}_BUILD_CMDS

Since the bump of libcap to 2.42, host-libcap unconditionally tries to
build a shared library, which fails on build machines where the static
version of the C library is not available.
This issue was reported upstream, who fixed it by two different
commits, which are backported as patches 0001 and 0002. They require
passing a DYNAMIC= value, which should be "yes" to enable dynamic
linking, or empty when not using dynamic linking.
However, other upstream changes broke our logic to support static-only
linking for the target. So we introduce a 0003 patch which extends how
the DYNAMIC flag is used to disable the build of the shared library in
the libcap/ folder. This allows to greatly simplify libcap.mk.
Note that the refactoring is mixed with the fix: the two are hardly
splitable. We need to be able to pass the same options at all steps, and
especially the staging step, otherwise some code gets compiled with the
host compiler, installed in staging, and thus fails the architecture
check later on.

Now that the libcap package has a patch that makes it build with
kernel headers < 3.0 (which was needed for the host variant of
libcap), there is no longer a need to have a dependency on headers >=
3.0 for the target variant of libcap.
All reverse dependencies of libcap are handled in this commit, except
lxc, which will be handled in a separate commit since it needs some
special solution.
The build of all those packages has been tested with a toolchain that
uses kernel headers 2.6.32, which is the oldest that our default glibc
version accepts to use.

Old kernels (before 2.6.36) were defining XATTR_NAME_CAPS in
<linux/capability.h>, but using XATTR_SECURITY_PREFIX and
XATTR_CAPS_SUFFIX which were defined in the kernel-only part of
<linux/xattr.h>.
In kernel 2.6.36 (commit af4f136056c984b0aa67feed7d3170b958370b2f),
the XATTR_NAME_CAPS definition was moved to the kernel-only part of
<linux/xattr.h>. It's only in kernel 3.0 (commit
1dbe39424a43e56a6c9aed12661192af51dcdb9f) that <linux/xattr.h> was
fixed to expose XATTR_NAME_CAPS and the related definitions to
userspace.
This is the reason why the target variant of libcap has a dependency
on headers >= 3.0 for the moment.
However, this doesn't solve the problem for the host variant of
libcap, which doesn't build properly on old systems.
To solve this, we simply add a patch that defines the missing
definitions. Their values haven't changed over time since they are
part of the kernel to userspace ABI.

Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed
from "prefer static libraries when possible" to "use only static
libraries". The former semantic didn't make much sense, since the user
had absolutely no control/idea of which package would use static
libraries, and which packages would not. Therefore, for quite some
time, we have been starting to enforce that BR2_PREFER_STATIC_LIB
should really build everything with static libraries.
As a consequence, this patch renames BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS, and adjust the Config.in option accordingly.
This also helps preparing the addition of other options to select
shared, shared+static or just static.
Note that we have verified that this commit can be reproduced by
simply doing a global rename of BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.

libcap provides a set of tools to manipulate capabilities, among which
`setcap(8)` and `getcap(8)`. A new menu entry has been added to install them.
[Thomas: mark the new option as requiring MMU support, because the
programs use fork(), and completely rework the new .mk logic as it
wasn't taking into account the BR2_PREFER_STATIC_LIB case.]
