mach: Use the host_get_time64 to replace the deprecated host_get_time for CLOCK_REALTIME when it's available
Check the availability of host_get_time64 and use it to replace
host_get_time for CLOCK_REALTIME when it's available. Fall back to
host_get_time if gnumach does not support host_get_time64 but the
gnumach headers do.
host_get_time is deprecated
See https://git.savannah.gnu.org/cgit/hurd/gnumach.git/commit/?id=569df850cd7badd1e36132ad3b44aa76a4d27c25
However, it's kept for backward compactbility.
* config.h.in: Add HAVE_HOST_GET_TIME64 config entry.
* sysdeps/mach/clock_gettime.c: Use host_get_time64 for CLOCK_REALTIME
when it's possible, fall to host_get_time otherwise.
* sysdeps/mach/configure: Check the existence of host_get_time64 RPC.
* sysdeps/mach/configure.ac: Check the existence of host_get_time64 RPC.
