I don't think its a Kconfig issue, see notes below.  However,
I have included my config file just in case I may be wrong.

Thank you

I at first assumed there was a bug in Kconfig and looked into this.
However, I found this solution is not a hack.  PRIV does not depend
on CORE.  Some header files in "PRIV CODE" check and see if CORE is
defined.  If it is not defined it appears to impliment dummy functions
that return an error code.  All but one of these dummy functions are
implimented.  This patch just implements one that was forgoten.
