minilua, by default, is compiled by the host machine as a
dependency for compiling the JIT/opcache extension. To
successfully cross-compile, this needs to be run under QEMU to
match the target architecture.
According to the [RFC](https://wiki.php.net/rfc/jit), only
x86 and x86_64 targets are supported.
