[PATCH] Update pattern to match when value is missing

[Yao Qi <yao at codesourcery dot com>]

Hi,
I get some fails when I test mingw native gdb,

> -var-create endvar * _end
^error,msg="mi_cmd_var_create: unable to create variable object"
(gdb)
FAIL: gdb.mi/mi-var-cmd.exp: create endvar

The test was added by this patch,

  [mi] Some error path fixes
  http://sourceware.org/ml/gdb-patches/2006-12/msg00107.html

and at that point, the error message was like:

-var-create endvar * _end
&"mi_cmd_var_create: unable to create variable object\n"
^error,msg="mi_cmd_var_create: unable to create variable object"
-var-update endvar
&"Variable object not found\n"
^error,msg="Variable object not found"
-var-delete endvar
&"Variable object not found\n"
^error,msg="Variable object not found"

and the pattern in the test matches them.  As time goes by, we updated
the error message,

-var-create endvar * _end^M
^error,msg="-var-create: unable to create variable object"
-var-update endvar^M
^error,msg="Variable object not found"
-var-delete endvar^M
^error,msg="Variable object not found"

but forget to update the pattern, so we get these three fails.

FAIL: gdb.mi/mi-var-cmd.exp: create endvar
FAIL: gdb.mi/mi-var-cmd.exp: update endvar
FAIL: gdb.mi/mi-var-cmd.exp: delete endvar

This patch is to adjust the pattern to match current error message,
and fix these three fails accordingly.  OK?

	message.
