Hm... I can't get any symbols out of luajit and I know it exports them
for linux and other platforms. "nm luajit" just gives "no symbols".
I think it has more to do with Efika MX Ubuntu's 10.10 rather than
luajit's Makefile, as other things are failing too (to find it's symbols).
Or the bintools nm is broken??

Some results on Efika MX smartbook (I'm very happy!):
Note: LuaJIT is running with (-joff, e.g. JIT off on this architecture
right now). But even without it, the results are impressive!
I would also test it on the Efika MX smarttop (very small cute device,
but I expect the same results).
This is running on Ubuntu 11.04 (just upgraded it from Ubuntu 10.10).
