The xclock_settime is a wrapper function on the clock_settime syscall to be used in the test code. It checks if the GLIBC_TEST_ALLOW_TIME_SETTING env variable is defined in the environment in which test is executed. If it is not - the test ends as unsupported. Otherwise, the clock-settime is executed and return value is assessed. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
