 * Test that pthread_condattr_setclock()
 *  shall set the 'clock' attribute in an initialized attributes object referenced by
 *  'attr'.
 *
 * Steps:
 * 1.  Initialize a pthread_condattr_t object
 * 2.  Set the clock to CLOCK_MONOTONIC (if the kernel has that capability)
 * 3.  Check that it was set successfully
 *
 * *FIX-ME: Need to find a better check on whether the kernel supports CLOCK_MONOTONIC
 *  clocks or not.
