I'm not sure that multiarch is actually quite ready for cross building
in the "biarch" -m32 manner, I think til now they have mostly
concentrated on being able to cross install runtime packages and proper
cross building (i.e. with $triplet-gcc not gcc -m32).

This is all based on vague observations on e.g. Debian devel and not
something I'm 100% sure on.

What happens if you add the -m32? Do the error messages differ?
