What is the OSX toolchain solution for inline asm with fat binaries? At some point we have to assume that people who are setting CFLAGS know what they are doing. We can't look for or protect against every silly thing they might do. Perhaps if --jitcapable is set and we're on darwin the thing to do is print a warning about fat binaries and --jitcapable being mutually exclusive things.
