-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] 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.

This change switches ARC tools to RC2 of the most recent arc-2016.03 version. Essentially once final release is ready version will be bumped again. ARC GNU tools of version arc-2016.03 bring some quite significant changes like: * Binutils v2.26+ (upstream commit id 202ac19 with additional ARC patches) * GCC v4.8.5 * GDB 7.10 More about changes, improvements and fixes could be found here: https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/tag/arc-2016.03-rc2 Also in this change we realign custom Buildroot patches for binutils and gcc for ARC tools. Looks like earlier most of arch-independent patches for binutils and gcc were either unintentionally removed or not even added in patch folders for ARC's binutils and gcc. Now arch-independent patches for binutils-2.26 and gcc-4.8.5 were added in package/{binutils|gcc}/arc-2016.03-rc2 folders. Build and run-tested in nSIM for both ARC700 and ARC HS38.
