Did you see this passage:
Selected kernel in our configuration uses certain version of compiler for build. Change compiler path to the directory, where this compiler is located (for example, if tools are compiled in /tmp/crosstools-2.95.3 then need add suffix /bin - /tmp/crosstools-2.95.3/bin –it shows location for cross-compiler executable files). Configuration setting for building is over, and then we can delete or add packages. These packages will be compiling automatically. If you want, you may show to include package in automatically compiling image OS which ready for install on target device.
when I build the rom, I also repeated the first step (the build of the tool chain) with corgi-arm-hardfloat-2.95.3-2.2.5-2.4.18 and /tmp/crosstools-2.95.3
And then set the corresponding option so that this gcc is used when compiling the kernel and not gcc-3.3.2.
note that I had a small problem during the compilation of orgi-arm-hardfloat-2.95.3-2.2.5-2.4.18 but it is simply that strip fails because there is no .so, I just commented out the line.
Note that I built a kernel for 860.
hope this helps.
