Subject: [PATCH] build: remove unused libatomic on ppc64, s390x
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The library is not necessary for ppc64 or s390x. It does no harm with
some linkers, but devtoolset-6 creates runtime dependencies on all link
libraries, even unused ones.
