A Tinderbox Jail is simply a version of FreeBSD for a given arch.  You
can use one Jail for i386 and one for amd64.  You can then create
different Builds which combine Jails and PortsTrees.  If you are just
building the same set of ports for all FreeBSD jails, then you probably
only need one PortsTree, and one Build for each arch.
