I use ggated/ggatec to export i386 device(s) to amd64 and run install on amd64. 2. I haven't tried this for a while and not sure if this still works. You can use nullfs mount over the i386.i386/tmp to hide binaries from there; if it hasn't changed, install targets don't build tmp and thus ends up picking from regular /bin and /usr/bin - there may be cases this fails.
