[PATCH][_GLIBCXX_INLINE_VERSION] Cleanup gnu-versioned-namespace.ver

[François Dumont via Gcc-patches]

    libstdc++: [_GLIBCXX_INLINE_VERSION] Cleanup 
gnu-versioned-namespace.ver

    Remove expressions for symbols in std::__detail::__8 namespace, 
they are obsolete since
    version namespace applies only at std:: level, not at sub-levels.
    libstdc++-v3/ChangeLog:

            * config/abi/pre/gnu-versioned-namespace.ver: Remove 
obsolete std::__detail::__8
            symbols.

Tested under Linux x86_64.

Ok to commit ?
