Merge tag 'localmodconfig-v3.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-kconfig

Pull localmodconfig fixes from Steven Rostedt:
 "Bill Pemberton added some changes to make streamline-config.pl work
  again as a stand-alone tool (outside of make localmodconfig).

  Also, he added a couple of updates to make the code be more "Perl
  proper".

  Added last minute fix to localyesconfig, that was the same as
  localmodconfig since v3.2, due to a change in the makefiles."
