The best way to work with this is to create a chroot, set the
appropriate variables (OSVERSION, UNAME_m, UNAME_r, etc), mount the
/usr/ports via nullfs (if you dare) and then call chroot to access the
chroot and build to your heart's content. There's an entry in the
handbook somewhere that better describes how to do it from scratch,
but my search skills are failing me and I don't have the full docs
tree checked out.
But yes, building amd64 on i386 probably won't work too well :)...
