Cherry-pick https://github.com/bazelbuild/bazel/commit/47696c94cac862ff80ece3873f4162f5815c7a32

Description of the problem / feature request:

Please cherry-pick 47696c9 into the next 5.x release.

Feature requests: what underlying problem are you trying to solve with this feature?

The current 5.0 release calls some native interfaces to get pids that are not present in Apple Silicon machines with our current JDK. That commit files the issue.

Bugs: what's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

Unfortunately, this reproduces with our internal JDK only. But we have validated that this commit fixes it.

What operating system are you running Bazel on?

macOS, in an M1 machine, with a custom JDK.

What's the output of bazel info release?

Both 5.0 and 4.2.2 repro this. In fact, every release up to (and including) 6.0.0-pre.20211110.1 reproduce it.

Any other information, logs, or outputs that you want to share?

Running bazel in the bazelbuild/examples repository, in cpp-tutorial/stage1, gives the following result:

There are merged conflicts when I try to cherry-pick this, that I don't feel confident in resolving, so can someone else create the cherry-pick PR?

I'll take a look. Thanks!
