When __TIMESIZE != 64 (like ARM32, PPC) the glibc expects separate definition of the __clock_gettime64. The HURD port only provides __clock_gettime, so this patch adds __clock_gettime64 as a tiny wrapper on it.

It is also safe to replace struct timespec with struct __timespec64 in deadline related structures as: - The __deadline_to_ms () returns the number of miliseconds to deadline to be used with __poll (and hence it is a relative value). - To calculate the deadline from timeval (which will be converted latter) the uintmax_t type is used (unsinged long long int).
