  test: make sure pthread is defined
  
  avoid warnings with any modern C99 compiler due to implicit function
  declaration for pthread_create, as shown by the following :
  
  test/regress_dns.c:2226:2: warning: implicit declaration of function
        'pthread_create' is invalid in C99 [-Wimplicit-function-declaration]
          THREAD_START(thread[0], race_base_run, &rp);
          ^
  test/regress_thread.h:35:2: note: expanded from macro 'THREAD_START'
          pthread_create(&(threadvar), NULL, fn, arg)
          ^
  test/regress_dns.c:2226:2: warning: this function declaration is not a prototype
        [-Wstrict-prototypes]
  test/regress_thread.h:35:2: note: expanded from macro 'THREAD_START'
          pthread_create(&(threadvar), NULL, fn, arg)
          ^
  
  $ clang --version
  Apple LLVM version 9.1.0 (clang-902.0.39.2)
