feat: Add support to cross-build youki on ppc64le architecture - #3578

Thanks for your first contribution.
Why do you think ppc64le support is necessary? I would like to know the use cases. Adding an architecture involves more than just adding a build process.

Hey @utam0k, thanks for taking a look at the PR.

The main objective is to have a Rust-based runtime option for the ppc64le (IBM Power) architecture. Right now, these environments are limited to runc and crun. This would allow some room for flexibility along with the benefits of having a Rust-based container runtime.

I completely agree that cross-building the binary is just the first step and that enabling CI/CD workflows and architecture-specific testing is the larger effort to ensure that the runtime works as intended on the given architecture.

I'd like to weigh in on your suggestions and inputs on the preferred flow to enable youki for ppc64le.

Thanks again!

Do you intend to use youki there?

Hey @utam0k,

Not for immediate production deployment, but as a first step, we want to enable the platform support so we can actively try the runtime out. Having the builds in place will allow us to test the runtime and confirm that it indeed works without any issues on ppc64le.

Please let me know if this sounds reasonable to you.

Thanks!

I would like to know if you intend to use it yourself. Supporting a platform that is not planned for use would impose a burden on the maintainers.
