  # We are using a recursive build, so we need to do a little thinking
  # to get the ordering right.
  #
  # Most importantly: sub-Makefiles should only ever modify files in
  # their own directory. If in some directory we have a dependency on
  # a file in another dir (which doesn't happen often, but it's often
  # unavoidable when linking the built-in.o targets which finally
  # turn into vmlinux), we will call a sub make in that other dir, and
  # after that we are sure that everything which is in that other dir
  # is now up to date.
  #
  # The only cases where we need to modify files which have global
  # effects are thus separated out and done before the recursive
  # descending is started. They are now explicitly listed as the
  # prepare rule.
  
  # To put more focus on warnings, be less verbose as default
