'-m32'?

However to make this useful one has to hack the library scripts to make
all installation to ${PREFIX}/lib32 I think.  If you are trying to
cross-compile on amd64, one possible better solution would be to
populate a pure 32-bit world (i.e. ./install.sh the 'base' distribution
to a directory and chroot into it with a mounted /dev).
