I recommend using an all.config file instead, which will allow you to
set not only the value for CONFIG_64BIT but also anything *else* you
want to exclude. Especially if you want things to actually be bootable,
that will be necessary.
The legacy i386/x86_64 values for $ARCH from before the merge are
basically no longer needed. The *only* thing they do is override the
CONFIG_64BIT setting, IIRC. So they ought to be able to go away in time,
and starting to use them in scripts now is probably not the best idea.
