Yes, that approach isn't expected to generally work for cross-building
ports for i386 on amd64. What is expected to work is compiling them in
an i386 environment on amd64 running a kernel with r210369/rev. 1.103
of sys/kern/kern_mib.c (r210855/rev. for 8-STABLE) in place
so the i386 binaries act as if they are running on native i386 without
hacks like MACHINE, UNAME_* etc being set. The cdrtools port is known
to be buildable for i386 in an i386 jail on amd64 that way.
