Comment 11 for bug 1766727

Cascardo asked me to review and sponsor the s390-tools debdiff to xenial-proposed. While I don't have a an easy way to test this change myself, I've verified that it matches the changes from Adam Conrad in Bionic and that the change looks reasonable. Cascardo ensured me that an SRU is not needed in Artful since linux-hwe-edge is not present there. I'm sponsoring this change to xenial-proposed.
