Actually, I think the correct way to build a linux kernel for i386 on an 
amd64 [1] system is to use 'linux32 make deb-pkg' [2]. With that no 
changes to the kernel build system should be needed at all, and I think 
with that you even should not need to set the ARCH variable.

It should also be possible to build a 64-bit kernel for i386 on amd64 that 
way using 'linux32 make ARCH=x86_64 deb-pkg'.

Untested, but AFAIK that should work. Sorry for not mentioning it earlier, 
but it's a command I've never really used myself and I keep forgetting 
about it :-/

Cheers,
FJP

[1] amd64 as in the Debian architecture, which also covers Intel 64-bit
[2] linux32 is in until-linux package and thus guaranteed to be available
