[PATCH 3/3] kconfig: add make localyesconfig option

[Steven Rostedt <rostedt@goodmis.org>]

From: Steven Rostedt <srostedt@redhat.com>

This adds the option localyesconfig to make. This is similar to
localmodconfig, but after it removes unnecessary modules it runs

  sed -i s/=m/=y/

on the .config file. It then runs "make silentoldconfig" to fix any
wholes that were created by the conversion of modules to core.

[ Impact: facilitate making a moduleless config ]
