Consider libsqlite3.so as canonical example. It doesn't itself use
pthread_create and just references e.g. the mutex functions. Those exist
as weak stubs in libc, so that a thread-aware library can use them.
If libpthread is not linked into the main program, the stubs provide
cheap short cuts for single-threaded programs. It doesn't work for
everything, but calls to pthread_create are a good decision point.
