After talking to the maintainer of make-kpkg on irc it seems this is
expected behaviour. This behaviour allows to build a 32bit kernel for
installation on amd64 or (more importantly) to build a 64bit kernel
for installation on i386.

If you really want a 32bit kernel for i386 you can use a 32bit chroot
or symlink i486-linux-gnu-{gcc,as,objcopy,...} to the 64bit binaries
and do a "real" cross-compile.

You could also change the architecture of the produced binary with

deb-reversion -k "sed -i 's/Architecture: amd64/Architecture: i386/'" DEBIAN/control"

or 

deb-reversion -k bash    and edit the control file yourself

PS: I just thought of one more thing. Try --cross-compile "".
