Browse Source 
Put AT_CLKTCK in ELF auxiliary vectors because some functions
use the value as described below.
1. GLRO(dl_clktck) set by
   _dl_aux_init (in glibc/elf/dl-support.c)
   or
   _dl_sysdep_start (in elf/dl-sysdep.c)

2. GLRO(dl_clktck) is referenced by
__sysconf (in glibc/sysdeps/posix/sysconf.c)
   __getclktck
      (in glibc/sysdeps/unix/sysv/linux/getclktck.c)
profil (in glibc/sysdeps/posix/profil.c)
   __profile_frequency
      (in glibc/sysdeps/unix/sysv/linux/prof-freq.c)
