Since Friday build-artifacts on s390x get stuck again, so we cannot run OST.
This is not a new issue, we have issues on s390x every few weeks.

I posted this patch to disable this job:
https://gerrit.ovirt.org/c/97851

We can enable the job when we have a reliable build slave again.

Here are some failed jobs:

- http://jenkins.ovirt.org/job/standard-manual-runner/758/
