Not the question you are asking, but if the goal is 32bit packages, you
will have a *much* better time creating a 32bit chroot and building
within it than relying on cross compilation.

Cross compilation relies on the package supporting cross-compilation,
which is a problem on pretty basic packages (perl, python). 32bit chroot
is indistinguishable for almost all packages.
