Line 118 GC_linux_thread_top_of_stack() relies on implementatio

LinuxThreads, namely that thread stacks are allocated on 2M boundaries

and grow to no more than 2M.

To make sure that we're using LinuxThreads and not some other thread

package, we generate a dummy reference to `__pthread_initial_thread_bos',

package, we generate a dummy reference to `pthread_kill_other_threads_np'

(was `__pthread_initial_thread_bos' but that disappeared),

which is a symbol defined in LinuxThreads, but (hopefully) not in other

thread packages.

void (*dummy_var_to_force_linux_threads)() = pthread_kill_other_threads_np;
