    hurd: Fix longjmp early in initialization

    When e.g. an LD_PRELOAD fails, _dl_signal_exception/error longjmps, but TLS
    is not initialized yet, let along signal state.  We thus mustn't look at
    them within __longjmp.

    * sysdeps/mach/hurd/i386/____longjmp_chk.S,__longjmp.S: Check for
    initialized value of %gs, and that sigstate is non-NULL.
