[Nirman Narang]

Any update on this?
I tried the latest version of qemu-user-static, it still fails with the same 
error.

Bug description:
  Steps to reproduce the issue:

  Register x86_64 host with the latest qemu-user-static.
  docker run --rm --privileged multiarch/qemu-user-static --reset -p yes

  Build the following Docker Image using following Dockerfile.s390x
  using command docker build -t test/crossbuild:latest-s390x -f
  Dockerfile.s390x .

  The build just hangs at RUN go install -v std


  Also, while running the same command inside s390x container on x86_64
  host, error Illegal instruction (core dumped) is thrown.

  Register x86_64 host with the latest qemu-user-static.
  docker run --rm --privileged multiarch/qemu-user-static --reset -p yes

  docker run -it -v /home/test/qemu-s390x-static:/usr/bin/qemu-s390x-
  static s390x/golang:1.14.2-alpine3.11

  Inside s390x container:

  apk update && apk add --no-cache su-exec curl bash git openssh mercurial make 
wget util-linux tini file grep sed shadow
  apk upgrade --no-cache

  #Disable cgo so that binaries we build will be fully static.
  export CGO_ENABLED=0
  go install -v std

  
  This gives the following error:
  Illegal instruction (core dumped)
