Stopped publishing /bin folders of CI builds

[Rajalakshmi-Girish]

What happened:

"/bin" folder is not published in CI builds. This broke all the kubeadm master jobs.

https://testgrid.k8s.io/sig-release-master-informing#kubeadm-kinder-master

What you expected to happen:

The CI builds published should contain bin folder with the executables.

How to reproduce it (as minimally and precisely as possible):

Look for bin folder in
https://console.cloud.google.com/storage/browser/kubernetes-release-dev/ci/v1.19.0-alpha.1.247%2B2fd8debe9b913f

Anything else we need to know?:

Environment:

• Cloud provider or hardware configuration:
• OS (e.g: cat /etc/os-release):
• Kernel (e.g. uname -a):
• Others:

This could be related to yesterday's change to lib/releaselib.sh in #1199, which would affect the push-build.sh script (which sources that library). push-build.sh pushes the build results of the ci-kubernetes-build* jobs, which are the artifacts that are pulled in several of our e2e tests.

I don't have time to look at this at the moment, but that (^^) should give people some places to start looking at and I'll sync up with the team later.

Potentially this line

release/lib/releaselib.sh

Line 749 in 01df93c

mapfile -t platforms < <(find "${release_stage}/client" -maxdepth 1 -mindepth 1 -type f -exec basename {} \;)
