ARC: bump tools to 2014.12 release

Browse source 
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

Fixes SIZE_TYPE to be "unsigned int" instead of "long unsigned int".
This makes size_t to be "unsigned" ssize_t which makes happy compiler on data
type checks.
Fix is taken from current development branch of GCC for ARC and will be a
part of the next release of ARC tools, so at that point patch should be dropped.

Redefine PTRDIFF_TYPE
Change of SIZE_TYPE from "long unsigned int" to "unsigned int" introduced
regression due to existing PTRDIFF_TYPE.
Now to fix regression convert PTRDIFF_TYPE to simple "int".
Fix is taken from current development branch of GCC for ARC and will be a
part of the next release of ARC tools, so at that point patch should be dropped.
