luajit: only available on x86(-64) hosts
The -m32 compiler flag is used for 32bit builds and host-luajit has
limited architecture support. Building for a 32-bit target on a 32-bit
host should always work, but we haven't tested that and it's very
unlikely that someone needs it. So just limit to x86(-64) hosts.
