Ken Dreyer fbb1ccc963 build: fix atomic linking with LTO on s390x ... Prior to this change, Fedora and RHEL 9 on s390x would incorrectly pass the HAVE_CXX11_ATOMIC check. As a consequence, the rest of Ceph would fail to link because of missing atomic methods "__atomic_load_16", "__atomic_store_16", "__atomic_compare_exchange_16". Mark this method so that it is not optimized out, even with LTO. With this change, s390x properly fails HAVE_CXX11_ATOMIC and falls back to HAVE_LIBATOMIC. Move the "BuildRequires: libatomic" RPM line out from the seastar+fedora conditional and into the main fedora+rhel conditional so that the HAVE_LIBATOMIC check will pass.
