The patch 2 in this patchset adding tracepoints for alarmtimers will build
failed on S390 platform, due to S390 defconfig did not define CONFIG_RTC_LIB
macro to define the rtc_ktime_to_tm() function which is used in this patch.
Thus we should add some ummy static inline functions in case CONFIG_RTC_LIB
is not defined.
