the SDK uses qemu for quite a bit of tasks internally, some recipes
depend on it for builds too for things which cant be done in cross
compile friendly ways. I think removing qemu might be a deep cut that
SDK wont survive for you. If you are looking for reducing the size you
might want to look at using a smaller image e.g. based on
core-image-minimal, if thats also too big for you. I would suggest look
elsewhere e.g. https://toolchains.free-electrons.com/
