y2038: Replace __clock_gettime with __clock_gettime64
The __clock_gettime internal function is not supporting 64 bit time on architectures with __WORDSIZE == 32 and __TIMESIZE != 64 (like e.g. ARM 32 bit). The __clock_gettime64 function shall be used instead in the glibc itself as it supports 64 bit time on those systems. This patch does not bring any changes to systems with __WORDSIZE == 64 as for them the __clock_gettime64 is aliased to __clock_gettime (in ./include/time.h).
