There's empty definition.
LIB_CLOCK_GETTIME =

clock_gettime is in both of them:
/lib # readelf -s librt.so.0 | grep clock
42: 00001cb4 68 FUNC GLOBAL DEFAULT 6 clock_gettime
44: 00001a78 172 FUNC GLOBAL DEFAULT 6 clock_nanosleep
64: 00001b74 88 FUNC GLOBAL DEFAULT 6 clock_getcpuclockid
/lib # readelf -s libc.so.0 | grep clock
166: 0000fcf4 72 FUNC GLOBAL DEFAULT 6 clock_gettime
514: 00011868 72 FUNC GLOBAL DEFAULT 6 clock_settime
537: 0000fa84 72 FUNC GLOBAL DEFAULT 6 clock_getres
762: 0002a588 56 FUNC GLOBAL DEFAULT 6 clock
but getcpuclockid is only in librt.
