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.

Download the portability patch into the buildroot tree.
This isn't nice but there really isn't another good solution for it.
The elfutils-portability.patch is version-dependent hence we already
have an older version for an older version of elfutils in the mirrors.
This causes hash check failures when fetching from sources.buildroot.net
But we can't remove (hence replace) the old version with the new one
since this would causee issues with older versions of
buildroot/elfutils for the same scenario.

Even when doing static builds, a shared library is built. This causes a
build failure under some circumstances, for instance when building for
MIPS + uClibc + static.
After asking upstream if it would be possible to add a configure option
to not build the shared library, the answer was that doing a static
build is not a good idea. Here is a small snippet of the conversation:
"Note that fully static builds are problematic. elfutils uses dlopen to
open the EBL backends (the CPU-specific support snippets), so even if
you link statically, the final binaries are still considerably dynamic."

Disable elfutils for avr32, because:

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.

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.

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.
