The ELDK now relies on Yocto, so it no longer has the funky
non-standard way of doing multilib. Also, we didn't mention that Yocto
toolchains/SDK are not suitable for usage with Buildroot. Therefore,
this commit rewords this part of the documentation to explain that
Yocto/OpenEmbedded SDKs cannot be used as external toolchains in
Buildroot, and why.

Now that we have eglibc and glibc support in the internal backend, and
no longer marked as experimental, a little bit of rewording is
needed. It is no longer necessary to indicate that uClibc was
historically supported as the only C library, and that the glibc
support is experimental. We also update the rest of the description to
be less uClibc specific.

There is no need to tell people that they should remove stamp files: they
should use the make <pkg>-reconfigure and make <pkg>-rebuild make targets
instead. We still keep an explanation about stamp files, just to give the
user an insight on how Buildroot works internally.

Using a relative path for O=... has limitations, since it is interpreted
relative to the Buildroot tree, and thus may lead to unexpected results.
For example, running this:
make -C buildroot O=my-O
will not create my-O in the current working directory, but as a
sub-directory of the Buildroot tree, here in buildroot/my-O
Explain this in the manual (as is similarly done for BR2_EXTERNAL).
Also add a note that $(O) will be created if missing.
Also change O=.. and -C .. to O=<...> and -C <...> to make it explicit
this is an ellipse, not a relative path.

Although it is possible to use relative paths, there are a few pitfalls
when doing so.
To avoid confusion for a (newcoming) user, use absolute paths in the
manual (as is done in examples for $(O)), since it is guaranteed to be
working without corner cases.

An entry is added to Makefile.legacy to warn users who have set

Still export BUILDROOT_CONFIG but pointing to some phony value, to
make sure that scripts that still use it fail in a predictable way.

Peter has just pointed me to the PGP signatures of the release tarballs,
which exist since he's been doing releases.
This was not obvious to me that the releases were signed, as there was
no info about it on the website.
So, add such links on the downloads page.

Currently, the manual uses the last modification date and time of
manual.txt in the generated manual.
This is confusing, especially for long-checked-out repositories where
the top-level manual.txt has not changed since the check out. Moreover,
the manual explicitly states 'generated on', which is confusing at best.
Use the current date and time instead.
