    Add documented libraries to LDFLAGS in the documentation Makefile.am
    
    gtkdoc-scangobj expects to have the libraries it's linking its scanner program
    to present in LDFLAGS. gtk-doc.make normally does this automatically for
    normal gtk-doc-enabled projects, but we need to do it manually.
