Change of SIZE_TYPE from "long unsigned int" to "unsigned int"
http://git.buildroot.net/buildroot/commit/?id=0f236c1fef669192c8f5cc8ef26e93da91438dc2
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.

I've applied your patch. However, I had to tweak a bit the commit log,
especially the title which wasn't matching the standard titles
we use in Buildroot.

Thanks,
