another Make (maybe) problem

[Robert Huff]

	While it's probably not related to the nominal issue, a deeper look at 
the full buildworld log found ten instances of this:

	While it doesn't stop the build process ... it would be nice to 
eliminate it as a possible contributing factor.
	1) Is this a problem, for this or anything else?
	2) Is there a way to fix it, short of a successful 
buildworld/installworld?
	(My version of "/usr/src/share/mk/bsd.subdir.mk", r263778, has 118 
lines/388 words/3377 characters.)

	Respectfully,
