added ppc64le support
This PR is adding power support to drone-git component. I have setup the Qemu user on x86 architecture, so with the help of that we are able to build and publish image on to dockerhub.
Hi @sumangalm-1 , I sent a similar pull request which was for s390x. In that case though, all the necessary code should be included. There are no other steps because it's using the thegeeklab/drone-docker-buildx image which has buildx already installed.
Here you say "I have setup the Qemu user on x86 architecture". Ok, sounds good. But does that require extra configuration beyond the pull request itself? If so, could you provide step-by-step documentation and explanation of what needs to be done?
