    testsuite: Fix g++.dg/ext/attr-copy-2.C for default_packed targets
    
    For targets where the byte-wise structure element layout is
    the same as for attribute-packed, you get a warning when
    that's specified.  Thus, expect a warning for such targets.
    Note the exclusion of bitfields.
    
            * g++.dg/ext/attr-copy-2.C: Fix for default_packed targets.
