Marek's first reply in the thread contains the solution:

  if you only need
  the KERNELRELEASE variable, then you do not need to depend on prepare.
  The main Makefile makes sure that silentoldconfig is ran and therefore
  KERNELRELEASE set for all targets except make *config.

which seems to suggest that "prepare" is not needed for either target.
