Gandalf is not a CentOS based buildbot but the self-built gcc is now
available under "/opt/rh/devtoolset-7/root/usr/bin/gcc" to reduce the
differences between the different buildbots and make it easier to move jobs
between different jenkins VMs. The only difference is that the gcc is
version 8.2 instead of 7.3.

Additionally, I have now also used the same CC and CXX setting for the
random config build bot (
Based on that I think gandalf can be used again for the tinderbox job and
therefore hopefully take a bit of load of the gerrit build machines.
