    libstdc++: xfail rename tests on rtems
    
    ::rename on RTEMS does not meet several POSIX requirements, despite
    compliance with C and C++ standards.  ::std::filesystem::rename, in
    turn, has requirements borrowed from POSIX, so it would have to be a
    lot more than a simple wrapper around ::rename on RTEMS, and even then
    fall short.
    
    Until RTEMS reimplements ::rename for POSIX compliance, expect
    filesystem rename tests to fail on it.
    
    
    for  libstdc++-v3/ChangeLog
    
            * testsuite/27_io/filesystem/operations/rename.cc: xfail on
            rtems.
            * testsuite/experimental/filesystem/operations/rename.cc:
            Likewise.
