Please don't mention RS/6000, we don't support that anymore.  The
architecture we do support is called Power or PowerPC; the target
triplets are powerpc*-*-*.  rs6000-*-* might still somewhat work, but
no one should use it anymore, and we probably should delete it.

Please say PowerPC here.

With that the patch is okay for trunk.  Thank you!
