Problem installing podman from source: sudo make install fails

[flowejam]

Issue Description

I was following the instructions here, as per the podman contributors guide. It causes a bit of unnecessary friction for newcomers that would be worth fixing I think. A similar issue was encountered previously: #19755 . In my case, the build worked, but installing with this command failed:
sudo make install PREFIX=/usr

I'm willing to submit a PR for this issue but was unsure of whether editing the docs or the Makefile would be preferred.

Steps to reproduce the issue

Steps to reproduce the issue

1. Run sudo go env GOOS without having /usr/local/go/bin added to secure_path

Describe the results you received

The issue in the Makefile is with these two lines:

GO ?= go                                                                        
NATIVE_GOOS := $(shell env -u GOOS $(GO) env GOOS)

so this error is encountered:
Required variable NATIVE_GOOS value is undefined, whitespace, or empty. Stop.`

Describe the results you expected

A successful installation from source after following the instructions here and running sudo make install PREFIX=/usr.
