This commit checks early if cross architecture building support via `qemu-user-static` (or similar tooling) is missing and errors in a more user friendly way. Note that there is no integration test right now because testing this for real requires mutating the very global state of `echo 0 > /proc/sys/fs/binfmt_misc/qemu-aarch64` which would make the test non-parallelizable and even risks failing other cross-arch tests running on the same host (because binfmt-misc is not namespaced (yet)).
