Details:

It appears that pattern rules don't work at all if they don't have a body
(recipe), even if they do have dependencies and thus aren't no-ops.


$ echo 'foo-%:' >Makefile; make foo-x
make: *** No rule to make target 'foo-x'.  Stop.
$ printf 'bar-%%:address@hidden bar $*\n\nfoo-%%: bar-%%\n' >Makefile; make 
bar-x;
make foo-x
bar x
make: *** No rule to make target 'foo-x'.  Stop.
$
