 Log Message:
 tests/lib/libpthread: Test unloading libpthread after lazy binding.
 
 If you dlopen libpthread and dlclose it again, the thread stubs like
 pthread_mutex_lock need to continue working -- a library might have
 calls to it in order to support thread-safety for threaded
 applications, but that library needs to continue working even in
 non-threaded applications after lazy binding of the libpthread symbol
 instead of the libc stub.
