I guess that depends on what you mean by "works".  The $* here evaluates
to the empty string since automatic variables are not valid anywhere but
inside recipes.

So, $(filter %,$(OBJS)) obviously matches everything.  But since OBJS
only contains things that you want to match, you don't notice.  If you
changed your OBJS value to include something that didn't match the
pattern you'd definitely see that it didn't work :-)
