Enable ppc64le support on node-sass

[krishvoor]

Hi,

Thanks for the very well articulated documentation that helped build node-sass from source and run the tests outlined successfully on IBM Power architecture (in short, ppc64le).

What is IBM Power architecture? It is a RISC architecture and is IBM's prodigy, IBM has recently made its ISA (Instruction Set Architecture) opensource, and in doing so, they have significantly contributed back to the opensource community at large. Many of the pioneers of banking and HPC industries today run on ppc64le architecture.

As an ongoing effort to enable open-source projects to which ppc64le architecture can add value, we are trying to enable this project. We have seen absolutely no deviation in build/test instructions. I plan to submit a PR to enable build/testing on ppc64le.

What would it take from us to enable ppc64le in the CI/CD pipeline? I see GitHub Action is being used for this project. As of now, this is not supported for native compilation on ppc64le. However, currently, we are enabled/ certified on Travis & Jenkins and lots of opensource communities have successfully used these.
