I thought the old way was just -pthread, and it would handle
everything.  I did a quick scan of the devel/ and net/ branches of our
ports tree, and of 43 thread-using ports, 36 of the ports simply add
-pthread.  Only 7 also add -D_THREAD_SAFE.

The only usage of _THREAD_SAFE in /usr/include is redefinition of
feof, ferror, clearerr, and fileno to *_unlocked.
