The s390x build has failed twice now with the same error:

https://download.sinenomine.net/epel/epel-7/noarch/epel-release-7-13.noarch.rpm: [Errno 14] HTTPS Error 404 - Not Found
Trying other mirror.

Error downloading packages:

  epel-release-7-13.noarch: [Errno 256] No more mirrors to try.

Seems unrelated to this PR.

@manselmi,

Thanks for the PR. The issue with s390x is related to nealef/clefos#5
I will try to workaround the issue today while waiting for the repo to be fixed.

@mayeut Thanks!
