My experience suggests that having a biarch cross compiler is, in fact,
often desirable.

dpkg-cross shouldn't need to "convert" library packages.  The same
packages that would be used on a native build are used; they'll be
Architecture: i386, even if they contain amd64 binaries, et cetera for
other platforms.
