[PATCH] D54338: Fix threads build on GNU/Hurd

[Kristina Brooks via Phabricator]

Doesn't `__APPLE__` imply `__MACH__` anyway outside of targets that are way out of scope of libc++? Since IIRC libc++ only runs on Darwin and only in usermode, which has the `__APPLE__` predefined macro even for stuff like PureDarwin .
