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]
