Build docker for OpenPOWER (ppc64le)

It’s a nightmare if you have a unsupported arch while building tools. I have tried to build docker for RHEL/CentOS, Ubuntu for ppc64le. It took me lots of time.

Fortunately, from 1.10, docker will support arch ppc64le officially. ppc64le will be the default arch for OpenPOWER system. As of now, docker code is still in reorg.
