Enable setting up of go on ppc64/ppc64le systems.

[kishen-v]

Description:
This change enables to install go on ppc64/ppc64le systems based on endianness.
The existing flow tends to pick ppc64 bundle for both big endian/little endian machines as os.arch() does not have the capability to determine the endianness, which leads to installing an unsupported bundle in the case of ppc64le.

Hi @kishen-v, Thank you for the contribution! just to clarify the practical impact of this change, GitHub-hosted runners currently do not support ppc64 or ppc64le architectures. Even if this PR is merged, it will not enable ppc64le on hosted runners, as the Go binary still cannot run without a matching runner. However, if you are using a self-hosted runner configured for ppc64le, the action should attempt to download the correct binaries.

Please try explicitly setting the architecture in your workflow as follows and verify that it is downloading the correct binaries:

- uses: actions/setup-go@v6
  with:
    go-version: '1.25.1'
    architecture: 'ppc64le'

Hey @gowridurgad,

Thanks for taking a look at the PR. You’re absolutely right that GitHub hosted runners don’t currently support PowerPC.

That said, since the existing code comment already notes that it’s future-proofed, this change helps make the action usable on self-hosted runners. Without it, users would need to maintain an additional workflow file just for the ppc64le architecture.

With the recent announcement about GitHub Actions support for IBM Power, IBM Z, and IBM LinuxONE
, this change would also help us plug in compatible runners seamlessly as that support expands.

Please consider this change to help enable easier support for Power based runners going forward.

Thanks!!
