Currently when using KCONFIG_ALLCONFIG with randconfig the choice options
are clobbered.  As recommended by Roman, this adds an is_new test to see
whether to select a new option or obey the existing one.
This is a resend of the earlier patch a couple of weeks ago, since there
was no reply.  Original thread is at http://lkml.org/lkml/2007/11/28/94
