    libstdc++: Add some makefile dependencies
    
    This ensures that wstring-inst.o and similar files will be rebuilt when
    string-inst.cc changes.
    
    libstdc++-v3/ChangeLog:
    
            * src/c++11/Makefile.am: Add prerequisites for targets that
            depend on string-inst.cc.
            * src/c++11/Makefile.in: Regenerate.
