[PATCH] Build a separate ZFS-enabled loader.zfs

This patch is a workaround to enabling ZFS support by default in the boot 
loader.  It enables building a loader.zfs which is a ZFS-enabled loader and 
changing zfsboot and gptzfsboot to use /boot/loader.zfs instead 
of /boot/loader.  I have only tested that things built ok, I have not 
boot-tested it as I don't have ZFS setup anywhere.  The patch is available at 
http://www.FreeBSD.org/~jhb/loader.zfs/.  You will also need to copy 
the 'loader.zfs/Makefile' file from that URL into a new 
sys/boot/i386/loader.zfs directory after applying the patch.
