Building the pretest recompiles many Lisp files, which it shouldn't IMO.

Looking at the Makefile's, I think the problem is in this snippet from
src/Makefile.in (near the end):

  /* Since the .el.elc rule cannot specify an extra dependency, we do it here.  */
  ${lisp} ${SOME_MACHINE_LISP}: $(BOOTSTRAPEMACS)

  ${lispsource}loaddefs.el: $(BOOTSTRAPEMACS)
	  cd ../lisp; $(MAKE) $(MFLAGS) autoloads EMACS=../src/bootstrap-emacs${EXEEXT}

  /* Dump an Emacs executable named bootstrap-emacs containing the
     files from loadup.el in source form.  */

  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) */
	  @: Compile some files earlier to speed up further compilation.
	  cd ../lisp; $(MAKE) $(MFLAGS) compile-first EMACS=../src/bootstrap-emacs${EXEEXT}

It goes like this: since temacs is built, the last rule says to
produce bootstrap-emacs${EXEEXT}.  The new bootstrap-emacs then
triggers the 2 rules before it, which rebuild loaddefs.el and
recompile the Lisp files in ${lisp} and ${SOME_MACHINE_LISP}.
