Likely, I misunderstood the request.  Mapping ppc64 to PPC64 is easy enough.
But currently, there is no direct support in the build/makefiles for ppc. See [OpenJDK supported platforms](https://wiki.openjdk.org/display/Build/Supported+Build+Platforms).
For anything other than the most trivial and obvious, someone who can build ppc and test should propose the changes.
