Well, true. Please use $(PTHREAD_LIBS) or similar instead.

The pthreads library is present at runtime, because it is allready
loaded by other parts of the program. However, it uses symbols of this
library und should thus be linked against on it.

Please try to compile the code with LDFLAGS="-Wl,-z,defs
-Wl,--as-needed" and you will encounter this issue.

Cheers,
Fabian
