That would be relatively hard, since you would need all the 32-bit build bits
and pieces floating around and, last I checked, you couldn't co-install them.

My solution was to create a chroot; traditionally, one of pbuilder or schroot
makes it easier to do this sort of cross-building in a robust fashion.


Otherwise, make sure that you are telling the build process to use the
appropriate cross-compiler and target architecture in debian/rules, make sure
you have the 32-bit libraries available to the target, make sure it doesn't
embed any non-standard library paths because of the crappy no-multi-arch
support, make sure it doesn't require plugins during build, and go for it.
