[PATCH] gdb.mi/mi-info-os.exp: Fix cross-debugger testing

["Maciej W. Rozycki" <macro@codesourcery.com>]

Hi,

 A live target is required for `-info-os' to work in non-native 
configurations.  Here's a fix for gdb.mi/mi-info-os.exp that removes the 
following failure:

(gdb)
Expecting: ^(-info-os[
]+)?(.*\^done,OSDataTable=.*[
]+[(]gdb[)]
[ ]*)
-info-os
^error,msg="Don't know how to get OS data.  Try \"help target\"."
(gdb)
FAIL: gdb.mi/mi-info-os.exp: -info-os

Tested with mips-linux-gnu (crossed from i686-linux-gnu).  OK to apply?

	* gdb.mi/mi-info-os.exp: Connect to the target in non-native 
	configurations.
