Cross-compilers can be used by setting X_COMPILER, Y_COMPILER, and CC to
the compilers to be used. The tests can be executed using a RUNUNDER script
much like the test-suite.
Also added Makefiles for testing the MIPS O32/N32/N64 ABI's in big/little
endian as well as with hard/soft-float (via SOFTFLOAT=1)
