  MFC 288829
  
    The latest version of lex requires the latest m4 to build, add a dependency
    when running the build-tools stage.
  
    The requirement is due to the -P flag used when running m4 from usr.bin/lex
    Makefile to generate skel.c.  With the old m4 that fails and the failure is
    ignored, resulting in an empty(-ish) skel.c, which leads to later build
    failures when the misconfigured new lex tool is run.
  
    This enables building -current (and 10-stable after MFC) on a stable-8
    system again.
