Change 'ls -l /bin' test to 'uname -m -n ...'

This test intermittently fails on OSX, an example::

    E           -rwxr-xr-x  1 root  wheel   106816 Sep  9 15:49 pax\r
    E         - -rwsr-xr-x  1 root  wheel    46688 Sep  9 15:59 ps\r
    E         + -rwsr-xr-x  1 root  wheel    46688 Sep  9 15:59 ps\r\r
    E         ?                                                     ++
    E           -rwxr-xr-x  1 root  wheel    14208 Sep  9 15:44 pwd\r
