You have to do that anyway for any kind of kernel work, no?

You could do that too, but you don't have to. Debian, like many other
Linux distributions, supports a wide variety of CPU architectures; it
can be run on embedded systems just as well as on desktop PCs or VMs.
I didn't say you have to use Debian, though, I just said I ran the
selftests on a Debian-based rootfs and that it was easy to prepare the
environment there. The Debian rootfs and the selftests were deployed to
the target board with the DSA switch on it, in case that wasn't clear.
