toolchain: bump ARC tools to arc-2016.03-rc2

Browse Source 
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.

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.
Once that new release happens this patch must be removed.
