    libstdc++: Tweak linker script to avoid conflict on Solaris
    
    The new symbols for the _M_construct<bool> function template match an
    existing pattern in the GLIBCXX_3.4.21 version, as well as the intended
    pattern in the GLIBCXX_3.4.34 version. That causes a linker error on
    Solaris.
    
    libstdc++-v3/ChangeLog:
    
            * config/abi/pre/gnu.ver (GLIBCXX_3.4.21): Make
            std::basic_string::_M_construct patterns more precise.
