    gnu: gtkmm@2: Override inheritance of certain changes from gtkmm.
    
    Recent changes made to gtkmm (67635125733b679ad16d59a40dc35f56cb5c0fb6),
    are not applicable to gtkmm@2, as the latter does not use meson.
    
    * gnu/packages/gtk.scm (gtkmm-2)[build-system]: New field.
    [arguments]: New field.
