    Use unsupported in 'require'
    
    This changes 'require' to use 'unsupported' rather than 'untested'.
    The latter doesn't really seem to be correct according to the DejaGNU
    documentation:
    
        Declares a test was not run.  `untested' writes in the log file a
        message beginning with _UNTESTED_, appending the `message' argument.
        For example, you might use this in a dummy test whose only role is to
        record that a test does not yet exist for some feature.
    
    The example there, and some text elsewhere, is what makes me think
    this isn't a great fit.  On the other hand, 'unsupported' says:
    
        Declares that a test case depends on some facility that does not exist
        in the testing environment.
