In Linux 2.6.39, CLOCK_BOOTTIME was added, which is essentially
monotonic time that accounts for time when suspended (rtc progresses, no
chance of it being reconfigured).

We use that one around NetworkManager:

http://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/src/NetworkManagerUtils.c#n1746

We essentially keep the CLOCK_MONOTONIC support so that the test suite
doesn't needlessly fail on el6 (2.6.32) build hosts.
