* sysdeps/generic/libc-start.c (__stack_chk_guard): New variable.
(__libc_start_main): Set __stack_chk_guard to

Increase it to 2.4.21 for sparc64.
* sysdeps/unix/sysv/linux/sparc/sparc32/clone.S: NULL terminate
backtrace by zero'ing out %fp. Store away flags, func_ptr,

and CTID arguments properly. Add RESET_PID handling.
* sysdeps/unix/sysv/linux/sparc/sparc64/pause.c: Rework so that we
do not invoke __sigprocmask(). We can always assume rt signals
are present on sparc64, so just do an inline syscall.

(SYSCALL_ERROR_HANDLER): If RTLD_PRIVATE_ERRNO, use rtld_errno
instead of errno.
