I'm not sure this answeres your problem but in recent kernels the
kernel adds the -m64 flag for amd64 automaticaly. The same should
happen for all other multiarch archs for both -m32 and -m64 as needed.

I also send in a patch for make-kpkg (applied in sid) for multiarch
cross-compile support using --arch <arch> --cross-compile '-'. This
tells make-kpkg to build for the arch but still use the normal "gcc"
instead of defaulting to "arch-os-gnu-gcc" as with other
cross-compiles.

Those two combined make building a kernel for "the other" arch of a
system simple.
