Hmm, I think I'd prefer that we just keep using _MIPS_SIM_ABI64.
Side note - this snippet of code shows another inconsistency... we have
_MIPS_SIM_NABI32 whilst the toolchain uses _ABIN32... No need to worry
about that here though. In short let's leave _MIPS_SIM_* alone in this
series.
Thanks,
Paul
