Removed -g from CFLAGS. There is a better way to build debugging
versions of the modules, and unconditionally putting -g in CFLAGS
has negative impact on the size of the resulting .ko object, even
now that debugging symbols are always stripped.

Add SBP-II target mode driver.

Though this is still incomplete and has some missing features such as
exclusive login and event notification, it may be enough for someone
who wants to play with it.

This driver is supposed to work with firewire(4), targ(4) of CAM(4)
and scsi_target(8) which can be found in /usr/share/example/scsi_target.
This driver doesn't require sbp(4) which implements initiator mode.

Sample configuration:

Kernel: (you can use modules as well)
device firewire
device scbus
device targ
device sbp_targ

After reboot:
# mdconfig -a -t malloc -s 10m
md0
# scsi_target 0:0:0 /dev/md0
(Assuming sbp_targ0 on scbus0)

You should find the 10MB HDD on FreeBSD/MacOS X/WinXP or whatever connected
to the target using FireWire.
