My comment #4 is not exactly, correct.

(gdb) target remote 192.168.1.14:1234
Remote debugging using 192.168.1.14:1234

This is expected to work correctly becuase gdbserver should pass target
arch information from server side to client side.

I have seen this happens correctly when gdbserver is from Ubuntu from
12.04 to 13.10 and gdb-multiarch being Ubuntu 12.04.

>From 14.04 onwards, I see the same problem reproducing again. So, a
regression in gdb. Re-opening bug. This is a bug for gdbserver (updated
package).

** Changed in: gdb (Ubuntu)
