    meson: Check linker support for --version-script
    
    There's a possibility that the linker doesn't support the
    `--version-script` option, so use `cc.get_supported_link_arguments()`.
    
    Also make sure to add the symbol map file to the `link_depends` options
    of the specific libraries.
