Subject: [PATCH] Added initial detection for GNU (Hurd) systems

Since they are quite similar to Linux, some just requires to add "GNU"
within the existing Linux detection commands. But some other commands
that requires the use of kernel (cpuinfo, model, battery) cannot be done
because /proc/cpuinfo and /sys does not exist in GNU Hurd.
