    gdb: Add i386-gnu-tdep to the list of objects for x86_64-*-gnu*
    
    When starting GDB on Hurd amd64, one will currently see the following
    warning:
    
      # gdb -q
      gdb: warning: A handler for the OS ABI "GNU/Hurd" is not built into this configuration
      of GDB.  Attempting to continue with the default i386 settings.
      (gdb)
    
    This happens because, in gdb/configure.tgt, the "x86_64-*-gnu*" target
    is not pulling in the i386-gnu-tdep.o object, which means that only
    64-bit debugging is currently supported.
    
    The fix here is to add i386-gnu-tdep.o to the gdb_target_obs for Hurd
    amd64.
