Fedora: Some tests fail for s390x arch

Since we got the arm test issues squared away I wonder if we could also see what's going on with s390x.

Because there's so much output I won't paste it all here but you can open the build log and search for "%check" to jump to where the tests are run.

https://kojipkgs.fedoraproject.org//work/tasks/910/76780910/build.log

Start with the linked Fedora build.log and search for "%check" to locate the s390x test output. Determine which tests fail on s390x and inspect the related project code and test setup. Done means the s390x test failures are resolved and the relevant tests pass on that architecture.
