i get that `grep -q` is something historically we've avoided, but i think it's
one of those bad habits we should just get out of.  i'll note that gnuconfig
uses `grep -q` in a bunch of places.

not that i'm going to spend time going through the codebase to update all the
usage, so if automake itself currently does it this way, OK.
