Details:

% cat Makefile
all: testdir/a testdir/b
%/a %/b:; touch $@
% rm -rf testdir
% mkdir testdir
% make
touch testdir/a
% make
touch testdir/b

The first make only makes "a" and forgets "b". I wondered if my
rules are actually right like this, but since the second time
make does make "b", it seems so to me. It works as expected when
I write two separate, but identical, rules for %/a and %/b.
