gcc: add new fix for the ARC 2014.08 gcc version

Browse Source 
This commit adds a new patch to the ARC 2014.08 gcc specific version,
that redefines PTRDIFF_TYPE from "long int" to "int".

The change of SIZE_TYPE from "long unsigned int" to "unsigned int"
http://git.buildroot.net/buildroot/commit/?id=0f236c1fef669192c8f5cc8ef26e93da91438dc2
introduced a regression due to the existing PTRDIFF_TYPE.

Now to fix regression the patch converts PTRDIFF_TYPE to simple "int".

The 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.
