    eal/unix: optimize thread creation
    
    Setting the cpu affinity of the child thread from the parent thread is
    racy when using pthread_setaffinity_np, as the child thread may start
    running and initialize before affinity is set.
    
    On the other hand, setting the cpu affinity from the child thread itself
    may fail, so the parent thread waits for the child thread to report
    whether this call succeeded.
    
    This synchronisation point resulted in a significant slow down of
    rte_thread_create() (as seen in the lcores_autotest unit tests, in OBS
    for some ARM systems).
    
    Another option for setting cpu affinity is to use the not portable
    pthread_attr_setaffinity_np available in FreeBSD and glibc,
    but not available in musl.
