Sorry, that should be

  yes 'n' | make oldconfig

and it turns out that this no longer works.  It used to work with the
old config system, but Kconfig gets confused by choices if the input
.config only has the selected choice and is missing the alternates.
For example, Kconfig accepts this

  CONFIG_X86_PC=y
  # CONFIG_X86_ELAN is not set
  # CONFIG_X86_VOYAGER is not set
  # CONFIG_X86_NUMAQ is not set
  # CONFIG_X86_SUMMIT is not set
  # CONFIG_X86_BIGSMP is not set
  # CONFIG_X86_VISWS is not set
  # CONFIG_X86_GENERICARCH is not set
  # CONFIG_X86_ES7000 is not set
  # CONFIG_M386 is not set
  # CONFIG_M486 is not set
  # CONFIG_M586 is not set
  # CONFIG_M586TSC is not set
  # CONFIG_M586MMX is not set

But will not accept CONFIG_X86_PC=y on its own.  Kconfig insists that
you manually select an option, even though only one valid option has
already been selected.  IOW, .config lines that are commented out
sometimes mean something to Kconfig :(
