[Richard Hughes <rhughes src gnome org>]

commit bcc6edc63f53d1332fd5b75ec4eedbe1841492ac
Author: Antoine Jacoutot <ajacoutot gnome org>

    gcm_calibrate_is_livecd() should be linux-only
    
    /proc/cmdline only exists on Linux and in this case used to check
    whether we are running out of a LiveCD.
