You are right. I actually used
$ make TARGET=mc1322x-ncb
I created mc1322x-ncb for Freescale Network Controller Board - came
with 1322XDSK-DBG from Freescale.
Not that I like this board, but I got this one before I found out
about redbee boards.
For anyone who is interested, I will upload a patch to create
mc1322x-ncb board under mc1322x platform.

Thanks. I noticed that webserver modules in apps/webserver use
'sprintf' and 'snprint' also, which are not available in printf.c in
cpu/mc1322x/lib.

I did not try WIP-2.4 yet, but I thought that I tried mc1322x-2.4.
I got a clean build. But the size of the webserver6.mc1322x-ncb.elf
file is 871K and the size of .bin file is 490K.
