I found another area of improvement to moz.build/config.status integration with Makefile/rules.mk. If we run config.status, execution of the current Makefile should restart (because Makefile or backend.mk may have changed). We should just need to add a new dependency or two and touch a file after config.status and we should be set. No clobber should be needed, just an update to rules.mk.

I think this should do it. Tested on OS X and it seems to do the right thing.
