AFAIK it is, but the _ABI{O,N}{32,64} isn't always defined. Current
Upstream CVS defines _MIPS_SIM properly for all Linux ABIs.

Older gcc had inconsistent definitions, a workaround is to check for
_MIPS_SIM_ABI32 instead of _ABI032. This will also work on modern
gcc as long as you #include <sgidefs.h>.
