This update was about a build via the zero configuration feature 
by just providing a Dockerfile.
Just to see if it works but it didn't.
I didn't find a git clone command in the log so I couldn't really 
tell.

A lot of things, such as RAM, timeout, custom git checkouts, 
custom command to build a docker container, environment 
variables, etc., can be configured in a cirrus configuration file.
So what I'm doing now is making a .cirrus.yml with a custom 
checkout, a shallow clone with --depth=1 of the master-ci branch 
should do the trick, using the container I made for building gcc.
Then I'll adapt the build-ci script for use with Cirrus-CI.
E.g. the dependency installation for instance isn't necessary by 
using a container that already provides all those.

I'm not sure if Johannes was referring to that script being a bad 
idea in hindsight. If so it's not a problem to define the 
necessary steps in the cirrus config.
