In general, it seems questionable to have cgcc handle an option named
identically to one in GCC but have it behave differently than GCC.

That said, I do think Sparse should handle different architectures
without requiring compilation of a "cross-Sparse"; it really just needs
a specs-equivalent for each architecture.
