This particular issue could be implemented just by adding
-DCLOBBER_CACHE_ALWAYS to CFLAGS (or CPPFLAGS if you want to be anal
about it). I suppose that no new buildfarm mechanism is required ---
someone just needs to set up an animal configured that way, and
scheduled to run only maybe once a week or something like that.
