Merge branch 'kconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild

Pull kconfig fix from Michal Marek:
 "This is a fix for a regression caused by my previous pull request.

  A sed command in scripts/config that used colons as separator was
  accidentally changed to use slashes, which fails when you use slashes
  in a value.  Changing it back to colons is of course not a proper fix,
  but at least it will be broken in the same way it had been for four
  years.  A proper fix is pending"
