Turn output folder into an order-only prerequisite

Browse Source 
This makes the output folder "required to exist" and not "required to be
more recent."

The folder's timestamp is updated when files are written into it. The
files inside depend on the folder existing. The result is that the WASM
and JS files are considered very slightly older than the folder that
contains them. The result is that the folder is up-to-date but it's
contents are not, thus re-building them and *again* updating the folder
timestamp. The makefile was stuck constantly rebuilding things that are
actually up-to-date.
