No, that's not a bug.

Not all platforms use _REENTRANT so checking for that wouldn't make
sense on those platforms.

It's the expected behaviour that if you don't link to libpthread then
the process is limited to a single thread, so if you try to launch
another thread you get an exception telling you there are not enough
resources to create the thread.
