    gitlab-ci: minimum build before the distcheck.
    
    The `make` step is mandatory before `make distcheck` (as far as my tests
    go), but probably we don't need such a thorough build (this is taken
    care of in its own step). So let's remove as much options as possible to
    get a minimum build and see how much time can be shaved off from this CI
    step as it is really far too long (even with my previous commit, it
    seems to be around 50 minutes for the whole make && make distcheck).
