[PATCH][_GLIBCXX_INLINE_VERSION] Fix test failure when no cxx11 abi and no dual abi

[François Dumont]

I ran testsuite with --enable-symvers=gnu-versioned-namespace config and 
1 test is failing because there is no dual abi in this mode and it 
defaults to COW string implementation.

    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.

Tested under Linux x86_64 w/o _GLIBCXX_INLINE_VERSION.

Ok to commit  ?

Thanks
