Subject: [PATCH] gnu: Add linux-libre-4.2.5

This older version of linux-libre is being added because it was found
that newer versions (or at least 4.3.3) of linux-libre were not reading
the hardware clock on (at least Libreboot-enabled) Thinkpad x200
machines.

* gnu/linux.scm (linux-libre-4.2.5): New variable.
