* sysdeps/generic/dl-osinfo.h (_dl_setup_stack_chk_guard): Take
one parameter. If non-NULL use it to initialize return value.
(_dl_setup_pointer_guard): New function.
* sysdeps/unix/sysv/linux/dl-osinfo.h: Likewise.
* sysdeps/generic/ldsodefs.h: Declare _dl_random.
* elf/rtld.c (security_init): Pass _dl_random to
_dl_setup_stack_chk_guard. Call _dl_setup_pointer_guard to initialize
pointer_chk_guard.
* elf/dl-sysdep.c (_dl_random): New variable.
(_dl_sysdep_start): Handle AT_RANDOM.
(_dl_show_auxv): Likewise.
* elf/dl-support.c (_dl_random): New variable.
(_dl_aux_init): Handle AT_RANDOM.
* csu/libc-start.c [!SHARED] (libc_start_main): Pass _dl_random
to _dl_setup_stack_chk_guard.
* elf/elf.h (AT_RANDOM): Define AT_BASE_PLATFORM and AT_RANDOM.
