The only thing you can do is use a sentinel file, like this:

    .sync: $(wildcard java/*.java lisp/*.lisp)
            synctool java lisp syncdir
            @touch $@

Now whenever any file is newer than the sentinel file make will see that
something has changed, and the synctool will be run, then the sentinel
will be updated.
