    libstdc++: Fix create_directories to resolve symlinks [PR101510]

    When filesystem__create_directories checks to see if the path already
    exists and resovles to a directory, it uses filesystem::symlink_status,
    which means it reports an error if the path is a symlink. It should use
    filesystem::status, so that the target directory is detected, and no
    error is reported.
