Try linking the program for Pthread support, and feed proper parameters to pthread_create.
The link is needed to make sure that the LIBS variable is set correctly, otherwise it might just be finding the definition but using the wrong link-time parameter.
Also, feed proper parameters to pthread_create to avoid -Wnonnull to cause a test failure (GCC/GLIBC).
