The functions __timer_gettime64 and __timer_settime64 live in librt, not libc. Use proper hidden aliases so that the callers do not need to set up the PLT register. Fixes commitscae1635a70("y2038: linux: Provide __timer_settime64 implementation") and562cdc19c7("y2038: linux: Provide __timer_gettime64 implementation").
