Pedro Alves 145e3ddb4b Fix gdb.base/a2-run.exp race
This patch fixes this racy failure, with the native-extended-gdbserver
board:

 Child exited with status 1

Note that the output is correct; it's just that inferior output
appeared after gdb's output, and the test doesn't handle that
correctly.

This comment isn't really correct, unfortunately:

	# waiting.  If we had already seen the status wrapper exit,
	# gdb_test_multiple/expect has no spawn ids left, and thus
	# returns.

That's true of expect in general, but I had missed / forgot that
gdb_test_multiple internally has extra matches using "-i
$gdb_spawn_id", so even if the caller clears all the indirect spawn id
lists, gdb_test_multiple will continue waiting.

So do a conditional exp_continue manually instead.

gdb/testsuite/ChangeLog:
2015-10-09  Pedro Alves  <palves@redhat.com>

	* gdb.base/a2-run.exp (maybe_exp_continue): New procedure.
	(top level): Use it in the run with no args test.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
