Which get's flashed through fastboot in a step below.

Don't build it. Use the prebuilt binary included in the repo:

Building Kernel

Use: 

make ARCH=arm panda_defconfig

And after building the kernel, do: 

cp arch/arm/boot/zImage ${MYDROID}/device/ti/panda/kernel

so it gets used in the .img generation.

Building Android Filesystem (AFS) with TI Codecs enabled

Use: 

lunch full_panda-eng

And build with: 

# For host with 4 CPUs:
make CC=gcc-4.4 CXX=g++-4.4 -j4
