The issue is that using the plugin interface makes breakage only detectable
when you are able to test a target, not by merely building it. That's bad
(of course only for those weirdo targets). We should _at least_ provide
an interface to internals that for example use the address of the pass
structure for pass placement instead of just the dump file name.
