    libstdc++: testsuite: call sched_yield for nonpreemptive targets
    
    As in the gcc testsuite, systems without preemptive multi-threading
    require sched_yield calls to be placed at points in which a context
    switch might be needed to enable the test to complete.
    
    
    for  libstdc++-v3/ChangeLog
    
            * testsuite/30_threads/this_thread/60421.cc (test02): Call
            sched_yield.
