The problem with this is:

1.  The Linux emulator isn't loaded by default.
2.  We're leaving the path clear for FreeBSD-native ELF binaries and
changing it would be a bad precedent.

The solution is probably closer to pointing big fingers at the
``linux_enable'' hook in /etc/rc.conf.  Handbook section maybe?
