It's a cross-compiler: http://userweb.kernel.org/~akpm/cross-compilers/

Here's a `make V=1':

rm -f include/config/kernel.release

set -e; if [ -L include/asm ]; then asmlink=`readlink include/asm | cut -d '-' -f 2`; if [ "$asmlink" != "powerpc" ]; then echo "ERROR: the symlink include/asm points to asm-$asmlink but asm-powerpc was expected"; echo "       set ARCH or save .config and run 'make mrproper' to fix it"; exit 1; fi; test -e $asmlink || rm include/asm; elif [ -d include/asm ]; then echo "ERROR: include/asm is a directory but a symlink was expected"; exit 1; fi
