The Hurd porting guidelines [1] recommend to use an  | gnu*

        canonicalize: make the right guess when cross-compiling to GNU
        * m4/canonicalize.m4 (gl_FUNC_REALPATH_WORKS): Match also "gnu*" to
        determine whether cross-compiling to glibc systems, so as to
        include GNU/Hurd.
