i386 is obsolete, and x86 should be used with the appropriate
32 bit configs.

I purged all i386 references quite some time ago, since they
can trigger other subtle errors.

Can you elaborate on what exactly what you are building, and
what fragments are in play that a 64 bit kernel is being
generated incorrectly ? We always go out of our way to specify
32 or 64 bit for that reason.
