Check build warnings in GitLab CI
Add a new set of jobs build-check:...
that would pass if there are no
warnings and would "fail" otherwise. Since the job is allowed to fail,
the failure would be reflected as a yellow job/pipeline status.
This should hopefully prevent warnings sneaking into master
unnoticed.
Note that currently there are two test failures due to !577 (merged)
