    libstdc++: Disable test for freestanding
    
    This test checks the exception-safety of std::stable_sort if copying a
    value throws. For freestanding we don't allocate in std::stable_sort
    anyway, and the exception thrown via __throw_runtime_error terminates,
    so disable the test.
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/25_algorithms/stable_sort/mem_check.cc: Do nto run
            for freestanding.
