8752516784 elfutils: propagate architecture dependency to comment
elfutils depends on !BR2_avr32, but this dependency was not properly
propagated to the comment about toolchain options. This commit fixes
that.

15ec3de799 package/elfutils: disable for avr32
Disable elfutils for avr32, because:
  - elfutils uses canonicalize_file_name, which came after uClibc-0.9.31.
  - avr32 uses a toolchain with uClibc-0.9.31

This patch lines up the comments in Config.in files that clarify which
toolchain options the package depends on.

381616e77a Introduce BR2_TOOLCHAIN_USES_{UCLIBC, GLIBC}
Currently, when we need to do a conditional on the type of C library
used, we need to take into account the three toolchain backends. As we
are going to add eglibc support to the Buildroot toolchain backend, it
would become even uglier, so this patch introduces two new hidden
options: BR2_TOOLCHAIN_USES_UCLIBC and BR2_TOOLCHAIN_USES_GLIBC, that
exist regardless of the toolchain backend. The entire Buildroot code
base is converted to use those options.

Note that we have intentionally created only one option
(BR2_TOOLCHAIN_USES_GLIBC) for both glibc and eglibc, since they are
essentially the same, as far as Buildroot is concerned.

3b595d512f elfutils: needs wchar
elfutils contains a call to wmempcpy, which is only available when the
toolchain has wchar support, so add the dependency.

Also display a comment if the toolchain dependencies are not met.

41f7e9b68a elfutils: make available on uClibc toolchains
We finally have all the pieces needed to allow the build of elfutils
on uClibc. Only the libraries can be built, the programs remain
available only for glibc/eglibc toolchains.

8515bb08f3 elfutils: towards uClibc support: disable po build
Building the po/ directory complains that the scripts in there have
been generated with gettext 0.17, while we use gettext 0.18 in
Buildroot. Since we don't care that much about po files anyway, just
disable the build of this directory.

07f6cdfb71 elfutils: towards uClibc support: FTS functions
The fts_*() functions are optional in uClibc, and not compiled in our
default configuration. The best option would be to migrate this
elfutils code to the nftw family of functions, but it requires quite
some work.

So we have several options here:

 *) Enable fts_*() functions in our default uClibc configuration. Not
    nice since only one package needs them (the help text of uClibc
    for fts_*() functions explicitly mention that they have been added
    to be able to build elfutils).

 *) Use gnulib, but it is quite heavy to setup, requires modifications
    to configure.ac, and other things.

 *) Copy the fts function from uClibc into elfutils source code. This
    is the solution used below. uClibc is LGPL, and elfutils is
    LGPL/GPL, so there should not be any licensing issue.

Of course, the fts_*() functions are only built if they are not
already provided by the C library.

8e6c06fb11 elfutils: towards uClibc support: argp-standalone usage
elfutils uses the argp family of functions, that isn't available in
uClibc. So, we add a dependency on argp-standalone if building with
uClibc, and modify elfutils source code to link against argp if
needed.

871846cad4 elfutils: make it possible to only install the libraries
Add and use a --{enable,disable}-progs configuration option to
selectively enable or disable the elfutils programs. Generally, on an
embedded system, the libraries are more useful than the programs, and
being able to not build the programs will make it easier to build the
elfutils libraries on uClibc.

75bd7d13b2 elfutils: new package
This patch adds a a package for elfutils. For now, the package is
glibc specific, as adding uClibc support for this package is quite
tedious, and will therefore be done through followup patches.
