Here we install some missing software needed for the kernel build.
We use 8 cores with make -j8 to speed up the build.
Most of the build is driver modules.
This kernel probably has all the drivers ever created for the kernel as I did not turn off any aspects of the kernel build
The kernel was STILL building when I stopped the video. Depending on your system this can take minutes or hours.
The more cores the better and the faster the storage the better.
