It's a bogus warning, it happens because you build Emacs
incrementally, starting from the previous build.  To make sure, say

  touch lisp/textmodes/text-mode.el

and then say "make" again -- this time there will be no warning.

AFAICT, the problem is that the first time loaddefs.el still isn't
updated, or something like that.

Such temporary warnings appear very frequently when Emacs is built
after an update (as opposed to a "make bootstrap").
