JIT now works on IRIX/mips, you need GCC for the synthetic opcodes:

Browse Source 
CC=cc CXX=CC ./configure --with-dgcc=g++

Also merge MIPSPro optimization flags from Basilisk II tree.

Note that I only verified the emulator works through the testsuite
(all tests passed, including AltiVec emulation)
