If `cargo` and `bindgen` is installed in your system, you should be able
to build qemu-system-aarch64 with configure flag --enable-rust and

the machine to the Rust one, so if something goes wrong you will see it
upon launching qemu-system-aarch64.
What version is required?
On my stock ubuntu 22.04 system, I get
/usr/bin/bindgen aarch64-softmmu_wrapper.h ...
error: Found argument '--formatter' which wasn't expected, or isn't valid in
this context
USAGE:

bindgen 0.59.1
I added version checks in the (yet unpublished) next version:
(Which we will also need to match with distro ones whenever possible)
+# FIXME: Latest stable versions, refine to actual minimum ones.
+msrv = {
