Tony Finch might know.

At a guess, to ensure it is run at least once - even when version.h
already exists. When originally written there was only version.h ;
version.sh was added later.

Possibly we could use a FRC: target, if the above guess is right.
We could use .PHONEY in gnu make, but it is not portable so would prefer
not.
