[PATCH 0/7] Gitlab CI improvements and fixes

[Thomas Huth]

Currently, almost all piplines of our Gitlab CI are broken, since there
has been a change in the default Debian-based container that causes the
QEMU build process to fail (aka. the "BITS_PER_LONG" macro problem).

We could likely either wait for the containers to get fixed, or we could
try to work-around that issue in the QEMU sources, but considering that
we test with Ubuntu (and thus Debian-based) containers in our Travis-CI
already, we should maybe do something different here and rather switch
our Gitlab-CI to some RPM-based distros instead, to get even more test
coverage. This is now done in the 5th patch. Along the way, there are
clean-ups and some minor improvements, and a fix to be able to build QEMU
with Clang again (last patch).

After applying this patch series, the Gitlab-CI shows "green" again:
