* thread_pthread.c (native_thread_init_stack): use get_stack.

Browse source 
patched by KOSAKI Motohiro [ruby-dev:40309]

* thread_pthread.c (ruby_init_stack): use get_stack
  on platforms which have pthread_attr_get_np.
  (FreeBSD, DragonFlyBSD and NetBSD)
  This is because FreeBSD and DragonFly BSD must use
  pthread_attr_get_np to get stack size of main thread,
  but Mac OS X and Linux with LinuxThreads must use getrlimit.
