Ceph

The following FTBFS happens on ppc64le in the OpenSUSE Build Service:

Though Ceph is not at fault here, we can easily work around the issue.

I would argue that adding the workaround is the correct course of action, because it preserves the ability to build master on ppc64le in the OBS.

Note that we have this same workaround in place for a number of other binaries:
