FWIW, I disagree on changing the default for mips64*-*-linux*, as N32
results in better performance for most applications. N64 is good for
large memory applications but slower.

I'm not opposed to specialized N32 od N64 configurations though, it
would at least save single-ABI systems from mulitlib hassles.
