    distrib/configure: Carry FFI include/lib paths from source distribution
    
    `FFILibDir` and `FFIIncludeDir` both show up in the `rts` library's
    package registration file.  We therefore must define them or else we'll
    end up with spurious `@FFILibDir@` strings in the package registration.
    
    In principle I think we could also take these as arguments to the
    bindist configure but this seems simpler and I don't want to verify this
    at the moment.
    
    Test Plan: Build bindist while passing `--with-ffi-libraries=...` to
    source distribution configure then try to install and use bindist.
