Umm, gcc also supports powerpc targeting embedded PowerPCs (eABI), and
IBM's AIX operating systems. I don't recall whether the MAC support
is currently in the GCC sources at the FSF, but I believe you can find
them at apple.com. Note, that the assembly conventions and calling
ABIs between Linux (& eABI) are very different from AIX (& MAC), so it
may or may not help you to target Linux.

The GNU assembler and linker target Linux and eABI.

Windows NT on PowerPC platforms has been officially dead, at least two years
now.
