package/libgtk2/0001-reduce-dependencies.patch

   1 Hack the configure.in file to add a "none" gdktarget which removes
   2 dependencies on graphic backends such as X.org or DirectFB. Gtk does
   3 not fully build in this mode, but it builds sufficiently to build the
   4 host tools that are needed to build the target Gtk.
