Enable ppc64le

Previously closed discussion: https://github.com/actions/setup-python/issues/613

Description:
Build python binaries for ppc64le and enable support for ppc64le in this repo.

Justification:
We recently launched GitHub Actions so open source projects can use runners on our Power and Z hardware. At this point, we are onboarding projects to use our GitHub actions service. Here is a blog post about our announcement and our official GitHub repo is located here.

This would greatly benefit a lot of open source communities to have the python action runner be supported on ppc64le. My goal is to eliminate inconsistencies with ppc64le and have parity with other archs (like with our newly released github actions).

Are you willing to submit a PR?
Yes absolutely. We can assist with any development, testing, and other needs if this feature request can be included in a roadmap.

Commencez par lire la discussion précédemment clôturée dans actions/setup-python#613, puis repérez les points d’entrée de build et de release de ce dépôt ; l’issue ne mentionne aucun fichier ni test. La tâche est terminée lorsque des binaires Python sont construits pour ppc64le et que l’action prend en charge cette architecture, avec une couverture pour le nouveau chemin.
