This seems to indicate that you are using some kind of add-on
packages: I cannot see gdbsrc-down and eos::toolbar anywhere in the
Emacs 21 Lisp files.

What are these add-on packages?  Is it possible that they are
incompatible with Emacs 21?  In particular, the error message "Toolbar
spec must be list or nil" seems an indication of some fundamental
incompatibility.
