Actually, this gets rid of the CONFIG_VIOCONS from my .config, but 
then I get another warning when I build:

Warning! Found recursive dependency: VT VIOCONS VT

Can anyone suggest something?
I think that your patch is mostly good/correct, but one more line
is needed on the VT side:  a deletion.

This works for me:

From: Randy Dunlap <redacted>

Make allmodconfig .config build successfully by making VIOCONS
available only if VT=n.  VT need not check VIOCONS.

With this dependency on EMBEDDED, you could as well simply remove

Removing the "default y" is wrong.
Oops, yes, agreed.

I don't see a way (using: make ARCH=powerpc iseries_defconfig,
which wants to enable VIOCONS) to prevent VT from being enabled
so that VIOCONS can be enabled.
With iseries_defconfig, CONFIG_VT is not enabled.
However, since VIOCONS is marked (Obsolete) and since the powerpc
people don't comment on this patch & problem, maybe Judith is the
only person who cares.
allmodconfig turns on CONFIG_EMBEDDED.
