You don't need to go to all that effort:

$ uname -m
amd64
$ echo "int main(void) { return 0; }" > t.c
$ gcc -c -m32 -o t.o t.c
$ gcc -m32 -o t t.o -B/usr/lib32
$ file t
t: ELF 32-bit LSB executable, Intel 80386, version 1 (FreeBSD),
dynamically linked (uses shared libs), for FreeBSD 8.2 (802510), not
stripped
