Because mkosi uses level 10, all I need to do is `rm >> debian/debhelper-build-stamp`.

There are several disadvantages to having build target not be phony: 1. I have to clean and rebuild the world when testing patches. 2. I have to clean and rebuild the world when testing overriden targets in d/rules. 3. Killing a build halfway and resuming becomes impossible, as the build directory causes make to consider `build` as done. Granted, in this particular case the discussion is a bit academic, since this is a single python script. But in general having `build` be phony is a great thing. -- Saludos, Felipe Sateler
