    thread_pthread.c: timer thread stack size
    
    * thread_pthread.c (rb_thread_create_timer_thread): define the stack
      size for timer thread at compile time.
    * thread_pthread.c (rb_thread_create_timer_thread): expand timer
      thread stack size to get rid of segfault on FreeBSD/powerpc64.
      based on the patch by Steve Wills at [ruby-core:59923].
      [ruby-core:56590] [Bug #8783]
    
    * thread_pthread.c (rb_thread_create_timer_thread): fix for platforms
      where PTHREAD_STACK_MIN is a dynamic value and not a compile-time
      constant.  [ruby-dev:47911] [Bug #9436]
