I used to think some Buildroot user might want to 'make dirs'. I
understand this is pretty useless, so I'll remove it.

It is rebuilt because legal-info-prepare-manifest is PHONY.

I could move the clean target to the 2nd patch, but actually this
maintenance burden is quite annoying, and is going to be even more since
this patchset will definitely have further changes.

Anybody has something against squashing the first 3 or 4 patches as
Arnout suggests?

It is rebuilt as well because $(1)-info-prepare-manifest is PHONY.
