Failing eclair-ARM64 job

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

Hi Simone,

As you might have noticed, all the eclair-ARM64 jobs have been failing
recently for the upstream Xen "staging" branch:

https://gitlab.com/xen-project/xen/-/pipelines/1056527466
https://gitlab.com/xen-project/xen/-/pipelines/1056520898

Although eclair-ARM64 is "allow_failure: true" still is the only job
currently failing and it would be nice to get it fixed, especially as we
are about to make gitlab-ci pipelines gating.

Cheers,

Stefano
