I've never needed anything more than order-only prerequisites along these lines.
http://www.gnu.org/software/make/manual/make.html#Prerequisite-Types
Here's a quick example.
dir/file : | dir/ ; touch $@
dir/ : ; mkdir -p $@
In this case dir/ is an order-only prerequisite of dir/file. The
timestamp of dir/ isn't considered when updating dir/file, only its
existence.
