I don't know.  What does happen whe you go to 64-bit mips?

AFIK the current model of MACHINE and MACHINE_ARCH doesn't work very well
where one architecture is a superset of another atchitecture.  A mips64
machine should be able to run mips32 binaries, but not the other way
around.  So what happens?  Does MACHINE_ARCH become `mips' and `mips64'
and the two are wholely incompatible?  Does a mips64 machine use a mips32
