This adds CFE tagged image generation in the BCM963xx target image Makefile. It has to generate its own LZMA compressed kernel because CFE is a LZMA nazi. It also seems that the Broadcom image tagger as well as CFE use AdvanceCOMP, which is based on a slightly older LZMA SDK. Anyways, some of the code is GPL, some of it is LGPL, so it might be that Broadcom owes some sources. Also, LZMA has a bug which causes it to generate different output when you are using stdin / stdout compared to plain files. I've just worked around the issue by using plain files.
