Sorry for missing the Kconfig entry.  It looks like init/Kconfig in
the "General setup" seems the best fit as that looks like where the
other build options are.  If this is ok I'll upload a new version of
the patch with the entry added.

I'm not sure what you mean about configs failing.  After adding this
option to init/Kconfig I was able to build fine using old and new
configs with and without the option set.  Is there something specific
you'd like me to test for?
