* `.make.osmo-ttcn3-hacks.clone`:

+ For example, if you `rm .make.libosmocore.autoconf`, libosmocore and all
+ projects depending on libosmocore will be rebuilt from scratch.
-In your `make*` subdir there are empty status files that are touched for every
-completed make target. From these, `make` can detect what needs to be rebuilt.
