pdfmark uses the suppression mechanism bounding box output
to find the anchor positions, but no images are involved.
The Postscript branch in suppress_node::tprint should be
perfectly okay with an empty image_filename. At the moment,
the entire "is_html / else postscript (or other device)" switch
is being skipped if we have no image_filename, resulting in
no output of the link anchor information for pdfmark.
