`easy-menu-add's body has been empty since at least 23.2, it was made
empty by [1: 59c7bf4].  As far as I can tell, it only exists to be more
compatible with XEmacs, so this is not a bug.

  (easy-menu-add): Don't precompute keybindings since those precomputed values aren't used any more.

I propose the following patch for emacs-25 to clarify that:

* lisp/emacs-lisp/easymenu.el (easy-menu-add): Make it into an alias of
`ignore', like `easy-menu-remove'.
