- Fix spurious rebuilds for (parallel) out-of-tree builds.
Make sure that the directories are order-only prerequisites. Otherwise we may have object files created after the timestamp of the directory was updated which would lead to spurious rebuilds (as some of the dentries may be older than the dir itself).
