    hurd: Assume non-suid during bootstrap
    
    We do not have a hurd data block only when bootstrapping the system, in
    which case we don't have a notion of suid yet anyway.
    
    This is needed, otherwise init_standard_fds would check that standard
    file descriptors are allocated, which is meaningless during bootstrap.
