MIPS64 sljit+bpfjit testing

Hi,

I'm going to add sljit+bpfjit support to MIPS3, MIPS32 and MIPS64 ports
but need to do some testing first. While I was able to setup gxemul
for MIPS3 and MIPS32 ports I don't know how to run emulated MIPS64 port.

Does anyone have any recommendations for setting up sbmips64-*
emulation?

Thanks,
Alex
