Most of the steps are similar for both qemu-amd64 and BBB targets.
Add reference link wherever required instead of repeating steps.

This is missing a step: Build a different image configuration, e.g.
switching to the RT kernel. Otherwise, you are now suggesting to flash
the same SWU on the disk as you write as full image, and we know that
this is broken (plus we have no error detection for that yet).
