    libstdc++: Fix test when dual abi disabled
    
    When !_GLIBCXX_USE_DUAL_ABI the old COW std::string implementation is being 
used
    which do not generate the expected error diagnostics.
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/std/time/format/data_not_present_neg.cc: Remove 
_GLIBCXX_USE_DUAL_ABI
            check.
