Comment 11 for bug 1630516

Things are a bit more complex as it also changes a build time self test.
These Tests are running, see https://launchpadlibrarian.net/228546427/buildlog_ubuntu-xenial-s390x.logrotate_3.8.7-2ubuntu2_BUILDING.txt.gz
The changes to the tests add new tests for these cases, so I think we want that.

And then there is a direct follow up fix for the fix which has to be considered as well.

OTOH T-Z are on almost the same version, so once done that should apply.
Working on the backports for the SRU now.
