GCC does generate O32. GNU binutils won't use the ARCH/ABI bits in the
ELF header in a lot of cases, though; and it emits a better way to
identify the ABI.
I don't think keying off MIPS II makes a heck of a lot of sense here...
depending on what SGI's tools put out you might want to default to O32
if no ABI tag bits are present, but that's a little shadier.
