Indeed, with "Multi-Arch: same" added to debian/control it is
possible to build tfortune on an amd64 system using the i386 version
of lopsubgen.

Then let's go through experimental. The patch shown below is identical
to the one you sent, except that I added the missing "Multi-Arch:
same" line, fixed a typo in debian/control (converstion) and provided a
commit message, using your original mail as the basis. If this looks
good to you, I'll push the change to the public repo for you to pick
up so that you can perform the necessary uploads.
Thanks

commit f9f4bdbf1dbaf3d9cd06243184ad33c311f91d7e

debian: Make liblopsub-dev usable for cross compilation.
In order to build a package such as tfortune which depends on the
lopsub library, we need the liblopsub shared library for the host
architecture, and we also need to run lopsubgen as a build architecture
executable. These things currently reside in the same binary package,
but for a cross build we need them to be installed for different
architectures.
This patch splits liblopsub-dev. The new liblopsub-bin package only
contains lopsubgen and its man page. Since the -dev package depends
on the -bin package, all existing uses will continue to work as
is. For a cross build, liblopsub-dev will continue to be installed
for the host architecture. liblopsub-bin will be installed for the
build architecture though as it will be marked Multi-Arch: foreign,
indicating that the architecture of the package does not matter for
interactions with it.
V2: Add missing "Multi-Arch: same" for liblopsub1t64, fix typo
