Cosmin Truta bb7e922914 ci: Introduce the CI_NO_BUILD flag
For testing purposes (e.g. wanting to see if "make distclean" works
correctly with and without building), as well as development purposes
(e.g. wanting to inspect the artifacts produced in the configuration
stage), add `CI_NO_BUILD` to the family of contrarians.
