[Buildroot] [PATCH v2] ARC: gcc - Fix SIZE_TYPE to be "unsigned int" instead of "long unsigned int"

[Alexey Brodkin]

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.
