Why do you use a custom target instead of the standard "pdf" target?
http://www.gnu.org/prep/standards/standards.html#Standard-Targets

The standard place to install PDF documentation (only by the standard "install-pdf" target, not the general "install") is $(pdfdir), which by default corresponds to $(prefix)/share/doc/<packagename>.

It might be nice to actually install these, but there's no standard place
to install them.  Nevertheless, it's nice to have the target around
because it shows how to generate PDFs.  It should make it easier for me to
regenerate the PDF for ovs-vswitchd.conf.db(5) on openvswitch.org, for
example.
