Add support for the s390x architecture

[fradaham]

As a team responsible for a self-developed integration platform implemented in asp.net core (currently 3.1) with the task of exposing IBM mainframe services, we have an interest to be able to run this platform as a linux container in the IBM zCX (zOS container extension) docker environment. But its a showstopper that there aren't any released linux images with .net (sdk and runtime) built for the s390x architecture used in IBM zCX. There are several other programming languages represented as linux docker containers for the s390x architecture, like python, java, ruby, golang, groovy, perl, just to mention some (see https://hub.docker.com/u/s390x/?page=1)). Is it possible to build .net core (sdk and runtime (asp.net core)) for the s390x architecture in a linux container? There exists a debian s390x docker image (https://hub.docker.com/r/s390x/debian).

@fradaham - Thanks for letting us know your interest in having support added for he s390x architecture. .NET Core does not currently support s390x therefore support would need to be added. Because of this, I am going to move this issue to the dotnet/core repo.

I couldn't figure out the best area label to add to this issue. Please help me learn by adding exactly one area label.

https://github.com/mono/mono supports s390x . Now that Mono is being unified with .NET Core, the easiest way to make progress on s390x would be to enable s390x Mono in https://github.com/dotnet/runtime .

This could have general interest. I have described a scenario that were interesting to us at "Running a hybrid application in Docker and zCX on ZD&T" Part 1 and Part 2.
