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.
