* Update docsys Makefile to support wwwdoc (#559)

The documentation is installed under `docs`, not `doc`, so this file has been updated.

Unnecessary 'touch'ing, the '>' redirect will create the file if it doesn't exist.
Also, the first redirect should be the single '>'.  Otherwise, multiple runs of this program will continue appending to these files.  They still work, its just a lot of setting and unsetting for no good reason.
