Actually you sort of must. You can build two packages, one foo
and one foo-amd64 or libfoo and lib64foo if that is worth it. The
program should be available for pure 32bit systems in Debian i386 and
the 64bit flavour would be a bonus for those that run a 64bit kernel.
So think about it. Will a 64bit binary have any benefits that warants
the extra complexity of building and maintaining biarch packaging?

Build-Depends: gcc-multilib, zlib1g-dev, lib64z1-dev [i386], ...

ldd runs the ld.so to get the libraries. That is bascially equivalent
to executing the binary and needs the full cpu and kernel support for
the binary format. So if you have a 32bit kernel you won't be able to
ldd a 64bit binary. Doesn't matter if it is amd64, sparc64, ppc64, ...
