Alyssa Ross 77f3a9a3aa gcc: broaden platforms
Okay, GCC might not technically support _every_ platform in
platforms.unix, but I think it would be easier to subtract those as
they're discovered, if that even matters, rather than trying to
exhaustively list every Unix it does support.

(I ran into this because I wanted to build GCC for NetBSD, which it
definitely supports.)

The GNU Compiler Collection includes compiler front ends for C, C++,
Objective-C, Fortran, OpenMP for C/C++/Fortran, Java, and Ada, as well
as libraries for these languages (libstdc++, libgcj, libgomp,...).
GCC development is a part of the GNU Project, aiming to improve the
compiler used in the GNU system including the GNU/Linux variant.
