You hit the nail on the head. Comment 'options GENERIC' out of your
config file. I think it's separate from the "swap on blah blah" string
because there's no way for the latter to conveniently control a
compile-time macro, and there's no easy way for the former to
conveniently control the swap config stuff. I'm talking through my
hat, of course, because I just started trying to learn about config a
week ago. But one thing I know: Comment out 'options GENERIC' and your
link will work fine, and your kernel will boot happily. At least it
worked for me.

Incidentally, I discovered this solution by looking at the source
code. The only reference to setconf() was inside
#ifdef GENERIC
...
#else

And furthermore, this was the only use of the GENERIC macro, so I
believe commenting out 'options GENERIC' is safe.
