uname -m is the correct invocation here (the other architecture string,
i.e. cpu arch rather than machine arch, is returned by arch -s and would
be wrong for this).
It isn't a big help for copy-and-paste though because the next section
goes on to use ${NAME}, and then a bit later on there's your-destdir and
your-releasedir...
