Building and installing podman from source unavailable on macos

[ssbarnea]

At this moment there is no documentation on how someone can build podman and install it from source on macos. This is a real problem as it prevents testing of code from master or testing patches.

For example at #7806 (comment) it is mentioned a patch that merged more than month ago but which cannot really be confirmed as working or not because there is no clear documentation on how to build it from source.

Ideally building and installing from source should be same as on linux, as the makefile should detect the platform and try the different build path specific to that platform.

This approach should provide a consistent hacker/developer experience, probably even more important than documenting the process. Not only this, but this would enable easy testing on github where macos hosts are available.

Sounds great. Interested in opening a PR for the Makefile to work correctly by default on a MAC?

[ssbarnea]

@rhatdan I would not mind helping with that task but at this moment there is zero documentation on how someone would even manually build podman from source on a mac and this makes testing impossible.

Shortly, show me some manual steps and I will automate them, or at least automate most of them.

There are lots of bugs where I would be pleased to help, like #8323 but lack of build docs does not help.

@baude @ashley-cui Could you help @ssbarnea out.

@ssbarnea I'll document but here's the gist:

make podman-remote-darwin creates the binary podman-remote-darwin which is just podman for mac (you should rename this to binary to just podman)
make install-podman-remote-darwin-docs creates the correct docs for macs.

As I said in the other PR. It would be very nice if the Makefile realized it is on a MAC and then just made the podman-remote binary as podman automajicly and then you used make install to install it.
