The rs6000-aix triples still work (for all GNU projects, not just GCC), but they obviously have not been tested for over ten years, and I'm trying to prevent any new use of those triples.

Most targets just die out slowly, and no one even tries to use them anymore, and then one day someone looks and the target is so broken and has been for so long, that it can just as well just be deleted there and then.
