Will you set DEFAULT_OPTIONS=yes here (for PR 64233), or should I test for 
INDEX_PRISTINE?

Is "s,$${LOCALBASE},/usr/local," "s,$${X11BASE},/usr/X11R6," appropriate
if INDEX_PRISTINE is not defined?

I always wondered why we don't have

.PHONY describe

and

.PHONY describe.$i

here. Any reasons for that?
