* sysdeps/arm/bits/setjmp.h, sysdeps/arm/fpu/bits/setjmp.h: Update
include guards.
* sysdeps/unix/arm/sysdep.S (syscall_error): Handle USE___THREAD and
RTLD_PRIVATE_ERRNO.
* sysdeps/unix/sysv/linux/arm/clone.S (__clone): Handle RESET_PID.
Handle new arguments.
* sysdeps/unix/sysv/linux/arm/vfork.S (__vfork): Use SAVE_PID and
RESTORE_PID. Use the right syscall error handler.

(__default_sa_restorer, __default_rt_sa_restorer): Add unwind
information.
