WhetstoneMP and mpmflops fails on 128-threads

[zubankov]

I tested 2 CPUs Loongson 3C6000/D with total 128 threads, and got errors on whetstonemp and mpmflops:

Fatal glibc error: pthread_mutex_lock.c:172 (___pthread_mutex_lock): assertion failed: PTHREAD_MUTEX_TYPE (mutex) == PTHREAD_MUTEX_ERRORCHECK_NP

Thread 34 "whetstonemp_loo" received signal SIGABRT, Aborted.
