libc generally isn't thread safe. libc_r (or libpthread, or whatever
the end result of the current shakeup will be called), is thread-safe.
The reason for that define is so that the C code you're working on (or
building via a port) can do different things depending on whether it
will be single-threaded or whether it needs to be thread-safe.
For example, your code might allocate and use mutexes if -D_THREAD_SAFE
