Source file was:
#include <pthread.h>

static void* test_func(void* data)
{
   return data;
}

int main(void)
{
   pthread_t thread;
   pthread_create(&thread, NULL, test_func, NULL);
   pthread_detach(thread);
   pthread_cancel(thread);
   pthread_join(thread, NULL);
   pthread_atfork(NULL, NULL, NULL);
   pthread_exit(NULL);

   return 0;
}

Looks as if  -lpthreads is missing.

I will try reokig that PR
