x86: Build and pass all tests on 32 bit cygwin

Browse source 
* check/lightning.c: Add workaround to conflicting global
	optind variable in cygwin binutils that have an internal
	getopt* implementation.

	* lib/jit_x86-cpu.c: Add a simple define ffsl ffs if building
	for 32 bit and there is no ffsl function.
