 The original PR says that it reduces the tor binary size by about 5.5
 kilobytes on macOS:
 https://github.com/torproject/tor/pull/1655

 However, it's a risky change if we're using weak linking on macOS or iOS
 (which I don't think we do, but other tor packagers might). I think if we
 try to bind all symbols at launch, and the current macOS doesn't have an
 optional symbol, we'll crash at launch. (Rather than testing if the
 optional symbol is NULL, or if we don't test, crashing when we use that
 symbol.)
