Actually there is no lucid toolbar, it is just native code and redisplay.  You 
get it even without using lucid.  Actually, a lucid tool bar replacement would 
be a good thing, but then lucid would be a requirement.

Anyway, I checked in the possibilty to have text in the tool bar.  Just for 
Gtk+ for now, I'm working on the native one.

See variable tool-bar-style for styles.  The default is taken from Xsettings 
(i.e. Gnome setting).

The code tries to generate a text for tool bar items based on key and caption. 
 This sometimes fails, so the property :label can be set on tool bar items. 
I've done this for a few items I saw at once, I'm sure plenty remain.
