Pedro Alves 1a3d890bcc [GDBserver]: Silence exits if GDB is connected through stdio.
If we make gdbserver gdb_continue_to_end actually expect a process
exit with GDBserver, we get many testsuite failures with the remote
stdio board:

-PASS: gdb.arch/amd64-disp-step.exp: continue until exit at amd64-disp-step
+FAIL: gdb.arch/amd64-disp-step.exp: continue until exit at amd64-disp-step (the program exited)
-PASS: gdb.base/break.exp: continue until exit at recursive next test
+FAIL: gdb.base/break.exp: continue until exit at recursive next test (the program exited)
-PASS: gdb.base/chng-syms.exp: continue until exit at breakpoint first time through
+FAIL: gdb.base/chng-syms.exp: continue until exit at breakpoint first time through (the program exited)
... etc. ...

This is what the log shows for all of them:

 (gdb) continue
 Continuing.

 Child exited with status 0
 GDBserver exiting
 [Inferior 1 (process 22721) exited normally]
 (gdb) FAIL: gdb.arch/amd64-disp-step.exp: continue until exit (the program exited)

The problem is the whole "Child exited ... GDBserver exiting" output,
that comes out of GDBserver, and that the testsuite is not expecting.

I pondered somehow making the testsuite adjust to this.  But,
testsuite aside, I think GDBserver should not be outputting this at
all when GDB is connected through stdio.  GDBserver will be printing
this in GDB's console, but the user can already tell from the regular
output that the inferior is gone.

Again, manually:

 (gdb) tar remote | ./gdbserver/gdbserver - program
 Remote debugging using | ./gdbserver/gdbserver - program
 Process program created; pid = 22486
 stdin/stdout redirected
 Remote debugging using stdio
 done.
 Loaded symbols for /lib64/ld-linux-x86-64.so.2
 0x000000323d001530 in _start () from /lib64/ld-linux-x86-64.so.2
 (gdb) c
 Continuing.
 Child exited with status 1
 ^^^^^^^^^^^^^^^^^^^^^^^^^^
 GDBserver exiting
 ^^^^^^^^^^^^^^^^^
 [Inferior 1 (process 22486) exited with code 01]
 (gdb)

Suppressing those two lines makes the output be exactly like when
debugging against a remote tcp gdbserver:

 (gdb) c
 Continuing.
 [Inferior 1 (process 22914) exited with code 01]
 (gdb)

		   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.
