    stubdom: make GMP aware that it's being cross-compiled
    
    Append --build and --host flags to GMP's configure script so that it
    knows it is being cross-compiled.
    
    This should fix the issue that GMP doesn't compile with gcc 6, because
    configure script won't try to test the host environment anymore.
