Sorry about that, Peter.

I get bitten by oldconfig all the time so I have a script to manage all
my configs. But it it would be nice if we had a way to express config
options transitions in kbuild.

I guess we could do something like the following and let it sit for a
release cycle to help people transition. Bit of a hack, but it worked
for me in my quick testing...
