IMHO we should "just" switch one of the Jenkins Linux builds to 32bit, not have
an other one. Preferable the gcc release one, as that has smaller object size,
if that is a concern for 32bit (linking etc). Should be fine just to cross-build
on 64bit in a 32bit chroot.

I remember there were some problems because of a missing 32bit Red Hat Developer
Toolset needed for the build, which was AFAIK the real reason to get rid of the
32bit builds - aehmm. Not sure that is now available.

And I / Rene was bitten a few times by broken 32bit builds, last was the
QVariant constructor ambiguity, so generally I'm all for it, if possible.
