That was LC_ALL=C, and I still see it here:

  emacs${EXEEXT}: temacs${EXEEXT} ${etc}DOC ${lisp}
  #ifdef CANNOT_DUMP
	  rm -f emacs${EXEEXT}
	  ln temacs${EXEEXT} emacs${EXEEXT}
	  -EMACSLOADPATH=${lispsource} ./emacs -q -batch -f list-load-path-shadows
  #else
	  LC_ALL=C $(RUN_TEMACS) -batch -l loadup dump
	  @: This new Emacs is as functional and more efficient then
	  @: bootstrap-emacs, so let us replace it.
	  -ln -f emacs${EXEEXT} bootstrap-emacs${EXEEXT}
	  -./emacs -q -batch -f list-load-path-shadows
  #endif /* ! defined (CANNOT_DUMP) */

The problem is, this part doesn't have it:

  bootstrap-emacs${EXEEXT}: temacs${EXEEXT}
	  cd ../lisp; $(MAKE) $(MFLAGS) update-subdirs
  #ifdef CANNOT_DUMP
	  ln -f temacs${EXEEXT} bootstrap-emacs${EXEEXT}
  #else
	  $(RUN_TEMACS) --batch --load loadup bootstrap
	  mv -f emacs${EXEEXT} bootstrap-emacs${EXEEXT}
  #endif /* ! defined (CANNOT_DUMP) */
