CI: Check all modules builds.

[thresheek]

While suboptimal and can be improved in future, I believe this is now needed to test if the modules compile at all.

I would prefer having arguments to cut in quotes, rather than escaped (so cut -d ' ' instead of cut -d\ ). Though up to you.

Thanks, I've changed the cut invocation to use quotes. I'll let the CI finish and will merge afterwards.
