"Architecture not supported" error in a armhf container on arm64 host
Metadata
Current evaluation
Snapcraft crashes with InvalidArchitecture 'armv8l' when run in an armhf container on an arm64 host. The bug is in craft-parts' architecture mapping. Fixed in craft-parts PR #697 which added armv8l to the platform machine variations map.
Suggested action: close stale
Reason: The underlying bug has been fixed in craft-parts PR #697 (commit 83679d41 'feat(info): support armv8l'), which added 'armv8l' to _PLATFORM_MACHINE_VARIATIONS mapping it to 'armv7l'. The current code in craft_parts/infos.py confirms armv8l is now properly handled. The issue is 935 days old with last activity 362 days ago, and the fix has been merged upstream, making this issue no longer applicable.

Issue body
### Bug Description
Snapcraft assumes the kernel architecture is the userspace architecture.
```
craft_parts.errors.InvalidArchitecture: Architecture 'armv8l' is not supported.
Make sure the architecture name is correct.
```
### To Reproduce
On e.g. a Raspberry Pi:
```
$ lxc launch jammy/armhf jammy-armhf
$ lxc shell jammy-armhf
$ snapcraft
### part yaml
_No response_
### Relevant log output
```shell
$ snapcraft --verbose --destructive-mode

The issue was resolved in Snapcraft 9.1 by adding native armv8l support, enabling successful builds in this configuration. | |
| #696 InvalidArchitecture: Architecture ‘armv8l’ is not supported | craft-parts | closed | Fixed an InvalidArchitecture error for 'armv8l' during armhf snap builds in aarch64/armhf LXC environments.

| #4627 Cannot build snaps in a 32-bit armhf container when running an arm64 kernel | snapcraft | closed | Closed without a public fix. An internal Jira ticket (CRAFT-2567) was created to track the architecture detection error, but no resolution or update was provided, leaving the issue deferred. | |
