For the general case, don't compile your stuffs with -mips2.  I once did
benchmarks and the gain by -mips2 was about 2%.  It's however ok to use
-mcpu=r4000 or similar because that will not generate MIPS 2 or higher
instructions, just schedule things optimal for the r4000.

I'm working on Linux/MIPS64.  Initially we'll only support 32-bit userland
but later on we'll support the full MIPS III / 64-bit bloat^H^H^H^H^Hfeatures.
