IMHO redundant. Since the answer is always "the last official release", with
a few exceptions during a transition, that answer is easier to remember than
a makefile target.

The release before 2.4.2, iow 2.4.0.

The system is simple. The warning is simply to remind people.

P.s. I added the note for overrideversioncheck too, as discussed, since it was
easy to do, and solve a few cases. But in general, I think it will drown out
in the noise. (maybe put a sleep there too? :-)
