could we add arm64 and ppc64le ?

could we add arm64 and ppc64le ?

I don't see a big problem.
several thoughts:

• take more time to build.
• we need to ensure it's stable. I would say two architectures that repeatedly stable built - it's already a win.
• we need to ensure all other images build on that architectures too. However, for this concrete case, it might be useful to build it unconditionally.

more time to build:
--> it's not done in parallel ?

idea was to bring amd64, arm64 and the two from IBMs
Usually when it's starting to work with more than once arch it's little thing to adapt.

@benoitf @sparkoo added linux/arm64,linux/ppc64le. Time of build increased from 12m->15m

@skabashnyuk maybe you could spin Docker Buildx rhel with another job so it's done in parallel

I'll experiment on that. At this moment I'm afraid errors during concurrent pushes. And logout probably has to be mode on another job too.
