Sorry, my fault it seems. I built the VM and checked the resulting  
modules, and it wasn't there. So I assumed there was something  
missing, and the generated source was not in src/ where it would  
belong, so I suspected that was the problem.

Checking again it looks like he V4L plugin was disabled by configure.  
The log says ...
