IIUC, I don't think you need to call uname -r again, because that
information is already in $canonical. build-aux/config.guess does:

  UNAME_RELEASE=`(uname -r) 2>/dev/null` || UNAME_RELEASE=unknown

and then

  ${UNAME_PROCESSOR}-apple-darwin${UNAME_RELEASE}

So I think it can just be merged into the main $canonical "unported"
test (see eg handling of sunos versions).

IIRC, we don't support that at all, anywhere.
