@dotnet/runtime-infrastructure @dotnet/area-infrastructure-libraries there are two build failures currently blocking me from flowing to internal:

Build FAILED.

[akoeplinger]

The first failure is on runtime-community linux-s390x build, it looks like it got broken by the azurelinux-3.0 image bump. You can ignore it for now.

[carlossanlop]

/ba-g Unexpectedly, BuildAnalysis captured a runtime-extra-platforms failure for tvos-arm64-mono #112436 and also a runtime-community failure for s390x #112435 , which is something I had not seen before. Maybe they were captured for being build failures, not test failures.

@lewing@steveisok@akoeplinger @dotnet/dotnet-runtime-triage would you block the 8.0 release based on these two build failures? (I think we never block on runtime-community issues, but I'd prefer to get a confirmation).

[carlossanlop]

I'll merge this PR to start the 8.0 builds. If we need to introduce a fix for any of these two failures, we will need the PRs submitted directly to the release/8.0 branch.
