Oops, all that was missing for that case was
an entry for coreutils.1 in the static dependency list.
Pity we can't use a GNU pattern rule here,
and portable suffix rules can't have prerequisites.
Note pattern rules seem widely supported, which is tempting.

Anyway I added coreutils.1 to the list and pushed.

thanks for the review,
Pádraig.
