ƒS )a`  Detect currently-running musl runtime version.

    This is done by checking the specified executable's dynamic linking
    information, and invoking the loader to parse its output for a version
    string. If the loader is musl, the output would be something like::

        musl libc (x86_64)

    :param archs: Sequence of compatible architectures.
        The first one shall be the closest to the actual architecture and be the part of
        platform tag after the ``linux_`` prefix, e.g. ``x86_64``.
        The ``linux_`` prefix is assumed as a prerequisite for the current platform to
