Support for `s390x` (`s390_64`) machine architecture
Is your feature request related to a problem?
The protobuf compiler protoc supports a few non-x86 machine architectures such as aarch64, ppcle, and s390x which are not supported by the gRPC plugin protoc-gen-grpc-java:
Describe the solution you'd like
It would be great if gRPC-Java supported the same machine architectures as Protocol Buffers out of the box.
With aarch64 there's already a non-x86 architecture supported by gRPC-Java and maybe support for the other machine architectures could be implemented in the same way.

I suspect it is going to be demand based as opposed to just matching the Protocol Buffers functionality. Is there a pointer to what specific changes are needed to support s390x? You could also contribute a PR to add that support.

Unfortunately I neither have experience with the s390x architecture nor do I know exactly what would have to be changed specifically in gRPC-Java.
My naive assumption is that a similar approach like the one taken for aarch64 support might work:

We tend to have these other architectures be user contributions because we can't test them. So if you contribute a change, at least we know it works for one user.
Since sept 2020 grpcjava works on IBM JVM using IBMJSEE2 on S390x with pull #7422
Is the issue here now resolved?
This issue is about protoc binaries for running the build on an s390x machine. With #7422 you can compile on another machine easily and deploy on s390x, but it is still annoying to run protoc as part of the build.
