I am a bit confused about this.  It looks like the current
mips-*-linux-gnu targets default to o32 when compiled for 64-bit targets
but the mips-sde-elf target defaults to n32 when compiled for 64-bit
targets.  I am not sure which default makes more sense but it seems odd
that the two targets have different defaults for the same architecture.
Do you know how the current state of affairs came to be with respect to
this difference in defaults?
