y2038: Replace __clock_gettime with __clock_gettime64
breaks benchtests with sysdeps/generic/hp-timing.h:
In file included from ./bench-timing.h:23,
from ./bench-skeleton.c:25,
from
/export/build/gnu/tools-build/glibc-gitlab/build-x86_64-linux/benchtests/bench-rint.c:45:
./bench-skeleton.c: In function ‘main’:
../sysdeps/generic/hp-timing.h:37:23: error: storage size of ‘tv’ isn’t known
37 | struct __timespec64 tv; \
| ^~
Define HP_TIMING_NOW with clock_gettime in sysdeps/generic/hp-timing.h
if _ISOMAC is defined. Don't define __clock_gettime in bench-timing.h
since it is no longer needed.
