commit 56b3c85096dc7863208c469d5318affc3ae468d0

    ci: Add build stage
    
    So far we are only performing a basic syntax check on javascript
    sources; it's time to test the C code as well. As mutter is tightly
    coupled, we bite the bullet and build it as well, either using a
    matching branch (if it exists), or current master.
