    [libstdc++] xfail noreplace tests on vxworks
    
    vxworks ignores O_EXCL in open, so noreplace open succeeds when it is
    expected to fail.  xfail the tests.
    
    
    for  libstdc++-v3/ChangeLog
    
            * testsuite/27_io/basic_ofstream/open/char/noreplace.cc: xfail
            on vxworks.
            * testsuite/27_io/basic_ofstream/open/wchar_t/noreplace.cc:
            Likewise.
