+Discover monotonic clock using compile-time check
+
+monotonic clock check does not work when cross-compiling.
+
+Upstream-Status: Denied [Does not work on OpenBSD]
+Signed-off-by: Jussi Kukkonen <jussi.kukkonen@intel.com>
+
+
+
+Original patch follows:
+
+When xorg-xserver is being cross-compiled, there is currently no way
+for us to detect whether the monotonic clock is available on the
+target system, because we aren't able to run a test program on the host
+system. Currently, in this situation, we default to not use the
+monotonic clock. One problem with this situation is that the user will
+be treated as idle when the date is updated.
+
+To fix this situation, we now use a compile-time check to detect whether the
+monotonic clock is available. This check can run just fine when we are
+cross-compiling.
