make install-world fails sometimes in Mac M1

Hi team, 

      We are using a script to install Postgres from source, the script works fine in ubuntu and Mac(intel) but mostly fails(works sometimes) in Mac M1. 

Configure and make world works fine. But fails during make install-world.

It's not like it fails every time, sometimes the same script works just fine. Sometimes after few retries it works.

I have also noticed that, if it works without issue, binaries generated does't work immediately. i.e when I tried to query pg_config, the command waits for sometime and gets killed. After a few retries, it works there onwards.

I'm wondering what could be the issue. I'm attaching the script to the same, kindly go through it and help me understand the issue.

Postgres Version: 11.14
Machine details: MacBook Pro (13-inch, M1, 2020), Version 12.4
