I hadn't tested the most basic default configuration and it is failing, I need some more time yet.

Hi

I've eventually completed this work.

This evolution will allow to build libstdc++ without dual abi and using cxx11 abi. For the moment such a config is only accessible through the --enable-symvers=gnu-versioned-namespace configuration.

    libstdc++: [_GLIBCXX_INLINE_VERSION] Use cxx11 abi [PR83077]

    Use cxx11 abi when activating versioned namespace mode.

Ok to commit ?
