* thread_pthread.c: get current main thread stack size, which may
  be expanded than allocated size at initialization, by rlimit().
  [ruby-core:60113] [Bug #9454]

* thread_pthread.c: rlimit is only available on Linux.
  At least r44712 breaks FreeBSD.
  [ruby-core:60113] [Bug #9454]

* thread_pthread.c (ruby_init_stack, ruby_stack_overflowed_p):
  place get_stack above others to get stack boundary information.
