True, this is how it's done in toolchain-builder project. But the goal here is
to provide the start-qemu.sh script at the end of the build, even outside of
Gitlab CI.

start-qemu.sh can be used outside of Gitlab CI, I'm regularly using Qemu
defconfig locally and getting the qemu command line from the readme is not
practical. That was the feedback I had from one user on previous iteration.

This series was started by my colleague Jugurtha about one year ago. Since then
toolchains update showed that Qemu runtime testing is necessary otherwise we can
end up with a non working defconfig (see issue with binutils 2.34 and sh4 kernel).

Thanks Yann for the review during the last Buildroot meeting!

Best regards,
