    libstdc++: Fix unused parameter warnings in <bits/atomic_futex.h>
    
    This fixes warnings like the following during bootstrap:
    
    sparc-sun-solaris2.11/libstdc++-v3/include/bits/atomic_futex.h:324:53: 
warning: unused parameter ‘__mo’ [-Wunused-parameter]
      324 |     _M_load_when_equal(unsigned __val, memory_order __mo)
          |                                        ~~~~~~~~~~~~~^~~~
    
    libstdc++-v3/ChangeLog:
    
            * include/bits/atomic_futex.h (__atomic_futex_unsigned): Remove
            names of unused parameters in non-futex implementation.
