bug#5162: 23.1.90; display-time broken in non-X build

[Sven Joachim <svenjoac@gmx.de>]

In non-X builds, the display-time command is broken, because the
find-image function is not defined:

,----
| Debugger entered--Lisp error: (void-function find-image)
|   (find-image (quote (... ...)))
|   (defvar display-time-mail-icon (find-image (quote ...)) ("/usr/local/src/emacs-23.1.90/lisp/time.elc" . 7689))
|   execute-extended-command(nil)
|   call-interactively(execute-extended-command nil nil)
`----

The following error messages from the build process (I used the 23.1.90
pretest tarball) might also be relevant:
