Add s390x and powerpc support to pipeline multi-arch build

[Deepali1999]

PR Description

Added s390x architecture to the pipeline build platforms, enabling multi-arch image builds for s390x.

What type of PR is this?

/kind feature

What this PR does / why we need it

This PR adds s390x to the multi-architecture build platforms in the Tekton pipeline definition (.tekton/kubernetes-sigs-kueue-main-pull-request.yaml).
With this change, images will be built for both linux/x86_64 and linux/s390x architectures, enabling support for s390x systems.

Note:

• The Dockerfile.rhel already supports multi-arch builds using TARGETARCH and TARGETPLATFORM.
• No changes were needed in the Dockerfile.
• E2E tests have passed for s390x locally.

Hi @Deepali1999. Thanks for your PR.

I'm waiting for a openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

And you should do the same for .tekton/kubernetes-sigs-kueue-main-push-request.yaml

@kannon92 Thanks for the review! I've made the following changes based on your feedback:

1. Fixed YAML format to .tekton/kubernetes-sigs-kueue-main-pull-request.yaml

2. Applied same changes to push pipeline: Updated .tekton/kubernetes-sigs-kueue-main-push-request.yaml to support s390x..

Please let me know if you need any further modifications!

We are not quite ready for merge things on main as our e2e tests are still in progress.

Waiting on #205

/hold

As I mentioned, our target for having our CI is hopefully by August 1st.

I'll unhold when our CI is functionally again. Sorry about this.

Just a heads up, you will need to apply these changes to the release-0.12 branch also?

How will you verify testing for S390z and power?

[Deepali1999]

How will you verify testing for S390z and power?

Thanks @kannon92!

Release-0.12 branch: I've created a separate PR (#233) for the release-0.12 branch with the same s390x and powerpc support changes.

For verification testing:

1. Local testing: I've tested the builds locally using cross-compilation.
2. CI/CD verification: The Tekton pipelines will automatically build and test on s390x/ppc64le platforms
3. Pipeline monitoring: I'll monitor the pipeline runs to ensure they pass on both architectures.

I mean can you run e2e with these images?

Install kueue on a s390z and powerpc and make sure the images are actually functionally.

[kannon92]

You could run the e2e tests with the quay repo. If those pass I’d be happy with merging this.

I have ran the e2e tests and it is completed successfully.

On power and s390z?

Just waiting for confirmation on e2e tests on power and s390z. Once I get that, I will add my approval and remove the hold.
