   Log Message:
   libatomic: fix aarch64 builds on NetBSD 9.x

   For aarch64, GCC expects a recent version of itself that accepts
   -mno-outline-atomics. Some packages pull in libatomic for aarch64,
   e.g., net/haproxy for __atomic_compare_exchange_16. (haproxy was
   compile tested after applying this fix.)
