[Guile-GTK] Conditionalize `gtk_link_button_set_uri_hook ()'.

From: Ludovic Courtès <[email protected]>

* configure.ac: Check for `gtk_link_button_set_uri_hook ()'.

* gtk-2.0.defs (gtk_link_button_set_uri_hook_interp): Conditionalize.

* gtk-support.c (gtk_link_button_set_uri_hook_interp): Enclose in
  `#ifdef HAVE_GTK_LINK_BUTTON_SET_URI_HOOK'.
