Fixes#11417
Cross-building the podman-remote documentation requires a functional
native architecture executable. However `make` only deals with
files/timestamps, it doesn't understand if an existing binary will
function on the system or not. This makes building cross-platform
releases incredibly accident-prone and fragile.
A practical way to deal with this, is via multiple conditional (nested)
`make` calls along with careful manipulation of `$GOOS` and `$GOARCH`.
Also, when cross-building releases be kind to humans and cleanup
any non-native binaries left behind.
Update the `Alt Arch. Cross` Cirrus-CI task to build release archives
for all Linux architectures supported by golang and podman. Update
the `OSX Cross` task to additionally build for the M1 (arm64)
architecture.
Finally, update the release process documentation to reflect the
new locations (Cirrus-CI task names) for the release archives. Include
a note about additional manual work being required to produce the
signed `.dmg` file for MacOS.
