Last time I looked, it didn't support native Win64 exceptions
(unwind tables in .pdata/.xdata sections). This is mandatory for
the LuaJIT Windows/x64 port.

Ok, so the #ifdefs pick the wrong exception handling model. But I
guess it would fail with the Win64 exceptions, too (next #elif).
And it would need to select LJVM_MODE=peobj LJVM_BOUT=$(LJVM_O)
in src/Makefile, too.
