    libstdc++: Fix unconditional -Werror in libbacktrace directory
    
    The -Werror flag should depend on the --enable-werror configure option.
    
    libstdc++-v3/ChangeLog:
    
            * src/libbacktrace/Makefile.am: Remove -Werror.
            * src/libbacktrace/Makefile.in: Regenerate.
