ok - i just walked through the process again on a different Mac
@moebiussurfing running through it again I got an error during the build_cross_gcc.sh part because gawk wasn't installed. I am wondering if you have incomplete build tools.
to remedy on the VM run
sudo apt-get install gawk
delete the CROSS_BUILD_TOOLS folder and start at the "Build the Cross Compiler" section
The original post now contains the gawk include. After this I was able to complete all of the steps
