* configure.ac: Only default to using the builtin disassembler if on GNU/Linux. This should be temporary, due to requiring /proc/self/exe. Correctly check $target_cpu for powerpc. * include/lightning/jit_ppc.h: Correctly implement jit_v_num. * include/lightning/jit_private.h: Declare proper prototype for jit_init_debug and jit_finish_debug. * lib/jit_ppc-cpu.c: Remove code to save/restore callee save float registers, as it is not required since those float registers are not usable currently. Change prolog and epilog generation to, at least comparing code, match what gcc generates in "gcc -O0", but it is still failing in Darwin PPC, apparently due to the __clear_cache call not being enough, as frequently it will also fail to execute, and the code buffer is all zeroes. * lib/lightning.c: Do not fail in jit_regset_scan1 calls due to passing 64 as argument on computers with 64 registers.
