Ceph

When trying to start ceph on a container (pacific v16.2.1) using cephadmin, ceph fails with SIGILL and crashes.

The issue seems to be related to https://github.com/facebook/rocksdb/commit/29f7bbef995bdf83098963799c66af742e95373f#diff-f4b9c0bf2f081ff23a370e62ccca17b723c40ab258ff12cd7901d4bca02901cf, so probably adding this patch will fix the issue.

Some extra information:
