A general (selftests) question: is there any build mechanism in the
kernel tree that is used to *expect* build failure?

Under certain circumstances, we would need klp-convert to fail and it
would be helpful to test for that. At the moment I am considered out of
tree tests that could exercise the code this way, but definitely prefer
anything that is already in-tree.

Thanks,
