    MGA DDX: make it possible to find EXA support
    
    Newer versions of the xserver stricter requirements on header order
    which caused the configure tests for EXA support to erroneously fail.
    Since XAA was already removed from an earlier version of xserver, the
    configure failure meant no acceleration was possible. Patch configure
    tests similar to r128.
