I've installed both of these (the former seeming obvious enough and
the latter not getting any comment from others after repeated tries
8-).

I'm still chewing on:

I'm thinking that MIPS_BFD_MACH isn't quite right as-is, but it's
probably easier for me to fix it than to describe in vague terms what
I think it should be and then have you try to implement it. 8-)

However, before I decide, I need to fiddle with it a little bit more.
