Maybe a better approach would be for the major mode to set an
`info-lookup-<something>` variable, instead.  This would also save us
from (require 'info-look), which would probably also fix the problem you
had with emacs-lisp-mode.

I guess we could do replace the above with

    (require 'm4-mode)
    [...]
    (defconst autoconf-info-lookup-thingy
      `(...
        :other-modes ,m4-info-lookup-thingy))
