Branch: CURRENT, Version: 15.1.0, Package name: libatomic-15.1.0, Maintainer: pkgsrc-users

Libatomic is a GCC-specific fallback implementation for atomics to
allow architectures that don't always provide a full set of atomics
to runtime-detect the existence of them, or fall back to the use of
mutexes.

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.)
