This is only for the GCC builds -- and yeah, it is a hack. I still
need to think a bit more how to do this better; although ultimately
the proper solution is to have `bindgen` use GCC like it does with
`libclang` and avoid this altogether. That way we can ensure the
bindings are correct, support plugins, etc.

Miguel
