Lukasz Majewski e9698175b0 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).
