22.17.6 says (for edition 2.9, GNU Emacs version 23.0.50 but that
for 22.1 is probably the same) :

                                              Major modes may replace
     the global bar completely by making `tool-bar-map' buffer-local
     and set to a keymap containing only the desired items.  Info mode
     provides an example.

Looking at info.el:

  (set (make-local-variable 'tool-bar-map) info-tool-bar-map)

and info-tool-bar-map is created using tool-bar-local-item-from-menu

Is that not clear?

gud.el provides another example.
