Hey Yauheni, can you CC me on the use-case explanation?

We currently do something really silly for the livepatch selftests on 
RHEL-7 for CKI that requires building them as pseudo OOT... in our case, 
we'd like to just be able to do something like make modules_prepare && 
make M= lib/livepatch, so perhaps a bit different... but I'd be curious 
for which problem you're currently trying to solve.
