The version notation on this line causes the emacs package version (can get
by `(assq 'emacs package--builtin-versions)` ) to be overwritten when
generating loaddefs, which in turn causes package.el to stop functioning
properly.

```
;;; Generated autoloads from emacs-lisp/cond-star.el

(push '(emacs 1 0) package--builtin-versions)
```
