Revert "Remove bin/podman.cross Make target"

This reverts commit c45b27f.

This commit was just wrong, local-cross depends on this target as it
calls a target like "bin/podman.cross.linux.amd64". Without this it is
just broken as there is no matching target.

$ make bin/podman.cross.linux.amd64
make: *** No rule to make target 'bin/podman.cross.linux.amd64'.  Stop.
