        PR libstdc++/24692
        * include/bits/atomicity.h (__exchange_and_add_multi,
        __atomic_add_multi): New, depending on _GLIBCXX_ATOMIC_BUILTINS,
        inline the atomic builtins.
        (__exchange_and_add_dispatch, __atomic_add_dispatch): Adjust.
        * configure.ac: Define _GLIBCXX_ATOMIC_BUILTINS when the atomic
        builtins are available.
        * configure: Regenerate.
        * config.h.in: Likewise.
