[PATCH v2] Fix mi_expect_stop for non-zero exit codes

[Simon Marchi <simon.marchi@ericsson.com>]

This patch was accepted almost a year ago, but I only recently received my
commit access. I submit it again to make sure it is still relevant.

Original submission: https://sourceware.org/ml/gdb-patches/2013-06/msg00736.html

The message displayed by gdb is different when the inferior exits with
zero and non-zero values, this fix takes that into account.

gdb/testsuite/ChangeLog:
2014-05-13  Simon Marchi  <simon.marchi@ericsson.com>

	* lib/mi-support.exp (mi_expect_stop): Expect message for
	inferiors that exit with non-zero exit code.
