Add a couple of architectures.

Hi Michael, this is about https://bugzilla.redhat.com/show_bug.cgi?id=1049209

The rel-eng says they need it (though I'm doubtful, they're all obsolete) If you'd really hate to merge these I'll find some other way to deal with the bug.

I smoke tested the stack but don't have the opportunity and resources to test the new specific architectures.
