[PATCH 0/3] automation: build qemu-system-aarch64 and use it for tests

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

Hi all,

Currently we are using Debian's qemu-system-aarch64 for our tests.
However, sometimes it crashes. See for instance
https://gitlab.com/xen-project/people/andyhhp/xen/-/jobs/939556527. It
is hard to debug and even harder to apply any fixes to it.

Instead, build our own QEMU as one of our test-artifacts, which are only
built once, then imported into each pipeline via phony jobs. Use the
provided qemu-system-aarch64 binary for our arm64 tests.

      automation: add qemu-system-aarch64 to test-artifacts
      automation: add a job to import qemu-system-aarch64 into the pipeline
      automation: use test-artifacts/qemu-system-aarch64 instead of Debian's
