So, that's definitely not a 64-bit kernel.

I think yes.  The first 2 dozen or so are definitely x86 specific and not 
applicable to x86_64.  I'm going to bet the others are too.  Notice this 
line:

> # using defaults found in .config

So, it's starting from your i686 config, and trying to use it to assign as 
many symbols as possible to the new x86_64 kernel.  Some of the symbols 
just won't exist.

When you 'make ARCH=x86_64 menuconfig', can you find the IA32 configuration 
options?
