[Buildroot] [PATCH] ARC: bump tools to 2014.12 release

[Alexey Brodkin <Alexey.Brodkin@synopsys.com>]

Now when new shiny tools are released by Synopsys we're ready for
version update in Buildroot again.

More details about arc-2014.12 release are available here:
https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/tag/arc-2014.12

Following patches were removed from GCC since they are a part of release
now:
 * 200-size_type_unsigned_int.patch
 * 300-ptrdiff_type_int.patch
 * 400-call-arc_hazard-before-branch-shortening.patch
 * 401-fix-length-attribute-for-casesi_load-pattern.patch
 * 402-fix-length-of-instructions-that-are-in-delay-slot-and-needs-to-be-predicated.patch
 * 403-update-casesi_compact_jump-instruction-length.patch

But since arc-2014.12 tools are still based on GCC 4.8 following patches
ar still relevant so moving to the new folder to match ARC gcc bump.
 * 100-libstdcxx-uclibc-c99.patch
 * 910-gcc-poison-system-directories.patch

Binutils are still based on 2.23 so following patch still makes sense:
 * 600-poison-system-directories.patch
