    libstdc++: Fix symbol version conflict in linker script
    
    The change in r11-4748-50b840ac5e1d6534e345c3fee9a97ae45ced6bc7 causes
    a build error on Solaris, due to the new explicit instantiation matching
    patterns for two different symbol versions.
    
    libstdc++-v3/ChangeLog:
    
            * config/abi/pre/gnu.ver (GLIBCXX_3.4.21): Tighten up patterns
            for basic_stringbuf that refer to __xfer_bufptrs.
