using lxd provider on s390 fails
Metadata
Current evaluation
LXD builds on s390 required Snapcraft 4.0 from the candidate channel; the report was later expired after 60 days without activity.
Resolution: closed stale
Reason: A maintainer directed the reporter to Snapcraft 4.0 for LXD use on non-x86_64 hosts. No further update or fix was recorded, and the janitor closed the report after 60 days of inactivity.

Issue body
When using the lxd provider to build on s390, it fails with the following message:
SNAPCRAFT_BUILD_ENVIRONMENT=lxd snapcraft
The LXD provider is offered as a technology preview for early adopters.
The command line interface, container names or lifecycle handling may change in upcoming releases.
Launching a container.
An error occurred with the instance when trying to launch with 'LXD': Create instance: Requested architecture isn't supported by this host.
Ensure that 'LXD' is setup correctly and try again.
The snap / project I am trying to build is: https://github.com/matrix-org/synapse, with some tweaks as I am attempting to debug an issue in the build.
I can successfully build using the host provider, remote-build option of snapcraft also fails, but with different messages.
