    gcc-configure: Enable the use of different symbol versioning
    
    While the gnu style for symbol versioning is the most usual,
    --enable-symvers[=style] can be provided several values,
    gnu, gnu-versioned-namespace, darwin, darwin-export, and sun,
    depending on users needs.
    
    Introduce the SYMVERS_CONF variable to allow the user to
    configure the symbol versioning in shared libraries.
