kconfig: add make localyesconfig option

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.
