Can't compile kernel module for RPI

[jleppert]

I've followed all the instructions but it's not working. At this point I'm wondering how to debug this? It's so painful to have to do these remote builds where you can't even get a shell into the build process to troubleshoot. I've tried the gcc-10 branch (should it be 9) but it doesn't work.

@jleppert Try the gcc-10 branch: https://github.com/balena-os/kernel-module-build/tree/gcc-10

@klutchell In the gcc-10 branch I had to install awscli from the testing repo too
