    libstdc++: Remove unconditional -pthread from test options
    
    This shouldn't be in the common options, it's already added for the
    relevant targets using dg-additional-options.
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/30_threads/jthread/jthread.cc: Remove -pthread from
            dg-options.
