Reimplement ONLY_FOR_ARCHS such that we know that this port requires newer
compiler features (which aren't very clear from the port itself). Probably
need to validate this on powerpc as we have clang available and gcc ports.

on non-clang architechtures. In addition, if there is no lang/gcc available
for the architecuture, we can't build it via that method either.
Rework archtecture disable to use ONLY_FOR_ARCHS and give a clearer reason
why this is being disabled on powrepc/mips/sparc64.
