[PATCH] testsuite: Add --status to runtest invocation

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

As discussed in this thread:

  https://sourceware.org/ml/gdb-patches/2016-01/msg00243.html

By default, if a test driver (a test .exp) ends with an uncaught
error/exception, the runtest command will still have a return code of 0
(success).  I think that if a test (or the environment) is broken and
the test ends up with an exception, it should be considered as failed so
that we can notice it and fix it.

Passing the --status flag to runtest will make it return an error if one
of the test it runs ends up with an uncaught error.

gdb/testsuite/ChangeLog:

	* Makefile.in (check-single): Pass --status to runtest.
	(check/%.exp): Likewise.
