I think it comes from gud-tool-bar-map.  gdb-get-buffer-create has
this:

            (setq-local tool-bar-map gud-tool-bar-map)

It works with a real mouse (here on MS-Windows, and I believe also
with GPM).  If xt-mouse-mode doesn't work with it, I guess it's some
bug.

It does here: if I click on "next", execution moves by one source
line.

Maybe.
