Comment 11 for bug 2025578

So I re-did the work on providing no also packages for non-s390x architectures,
based on feedback from @xnox and @schopin
and incl. an add. upstream commit as patch to avoid random build issues (thx to @mhartmay).

The re-worked packages build fine locally on s390x and amd64 and in PPA - builds are available here:
https://launchpad.net/~fheimes/+archive/ubuntu/lp2025578

I also did installation and upgrade tests, that led to some further tweaks needed (Breaks and Replace, postinst now s390x specific etc.), but all that is included, too.

I'm attaching here the two debdiffs (for s390-tools and s390-tools-signed).
