Why don't you just use "mkdir -p"?

        default: a/b/c/

        a/b/c/ : ; mkdir -p $@

To answer your question, there's no way to do that without using a
complicated expression combining $(foreach ...) and $(eval ...) and
probably a few other functions such as patsubst to turn / into space
etc.
