I gave it some thought. Currently we only have mips64{,el}-linux-gnu,
which, to make matters worse, defaults to a n32 compiler with
multilibed o32/n32/n64 libraries. IMHO the best thing to do is to
introduce a completely separate set of triplets for the more advanced
single-ABI mips configurations. E.g:

mipsn32-linux-gnu
mipsn32el-linux-gnu
mipsn64-linux-gnu
mipsn64el-linux-gnu

The distinction between mips64 and mips_n_64 is a bit subtle, but
I don't see a better way while keeping the scheme relatively simple.

Comments?
