At the risk of stating the obvious, note that there is a trivial
work-around for this - there is nothing special about dot in patterns,
so you could merge the dot into what % matches to make it non-empty:

MOTD%log: MOTD%txt MOTD%in

... or, of course, merge the D in from the other end:

MOT%.log: MOT%.txt MOT%.in
