Comment 5 for bug 1808147

Right, I had overlooked that unit tests are intentionally disabled on s390x and all other big endian architectures, and thus libcppunit-dev is excluded from the build dependencies on s390x.

It is unclear to me whether the smoke tests could eventually be made to run and pass on s390x, but for the moment it seems reasonable to just skip the failing autopkgtest on that architecture, which I've done with https://git.launchpad.net/~libreoffice/ubuntu/+source/libreoffice/commit/?id=7c69bd0dccbfc377fe644042e0dad75f142c04f8.

1:6.1.3-0ubuntu9 is now building in disco-proposed.
