Hmm. Yeah, that's a bug. I think that's an existing bug, though. I feel
like I scratched my head on that too. I will see if there is a sensible
way to have Kbuild "notice" that -- I hope there's an easier way to
invalidate all object files instead of adding all the plugins as a dep
to all .o builds. O_o
Thanks for the heads-up!
