Allow C99-depending features of libstdc++ with uClibc
The libstdc++ code is fairly restrictive on how it checks for C99
compatibility: it requires *complete* C99 support to enable certain
features. For example, uClibc provides a good number of C99 features,
but not C99 complex number support. For this reason, libstdc++
completely disables many the standard C++ methods that can in fact
work because uClibc provides the necessary functions.
This patch is similar and highly inspired from
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58393, but implemented in
a way that doesn't involve changing the configure.ac script, as
autoreconfiguring gcc is complicated. It simply relies on the fact
that uClibc defines the __UCLIBC__ definition.

Subject: [PATCH] PR other/56780
* libiberty/configure.ac: Move test for --enable-install-libiberty
outside of the 'with_target_subdir' test so that it actually gets
run. Add output messages to show the test result.
* libiberty/configure: Regenerate.
* libiberty/Makefile.in (install_to_libdir): Place the
installation of the libiberty library in the same guard as that
used for the headers to prevent it being installed unless
requested via --enable-install-libiberty.

libiberty: fix --enable-install-libiberty flag [PR 56780]
Commit 199570 fixed the --disable-install-libiberty behavior, but it also
added a bug where the enable path never works because the initial clear
of target_header_dir wasn't deleted. So we end up initializing properly
at the top only to reset it at the end all the time.

Subject: [PATCH] UPDATE: Fix handling complex PIC moves.
fwprop is putting in the REG_EQUIV notes which are involving the
constant pic unspecs. Then, loop may use those notes for
optimizations rezulting in complex patterns that are not supported by
the current implementation. The following piece of code tries to
convert the complex instruction in simpler ones.
The fix is done in development tree: [arc-4.8-dev b55922d]
and will be a part of the next release of ARC GNU tools.
Once that new release happens this patch must be removed.

Subject: [PATCH] UPDATE1: Fix handling complex PIC moves.
The arc_legitimate_pc_offset_p condition is too lax. Updated it.
The fix is done in development tree: [arc-4.8-dev f00b0f1]
and will be a part of the next release of ARC GNU tools.
Once that new release happens this patch must be removed.

Subject: [PATCH] Don't allow mcompact-casesi for ARCv2
The compact casesi is not working for arcv2 processors family as it
makes use of the add_s rx,rx,pcl instruction which is only valid for
arc6xx and arc700 processors. Also not having this instruction makes
no much sens to change the compact-casesi pattern to use normal add
instructions as it nullifies the advantage of short instruction use.
The default casesi pattern betters suits the arcv2 architecture.
The fix is done in development tree: [arc-4.8-dev 0946382]
and will be a part of the next release of ARC GNU tools.
Once that new release happens this patch must be removed.
