Simon Marchi 921b2bc73e gdb/testsuite: set sysroot in gdb.server/stop-reply-no-thread-multi.exp
I get some random timeouts in this test due to big debug info taking a
lot of time to read through gdbserver.  When host and target are on the
same machine, clear the sysroot parameter so that GDB reads the files
from the local file system, as we already do in many tests.

I agree with what Pedro says here:

  https://sourceware.org/pipermail/gdb-patches/2019-March/156568.html

that if this is bad for us, it's also bad for users, so we should be
fixing the slowness instead.  But so far nobody seems to be working on
it, and the testsuite timeouts are getting in the way, so I think this
"set sysroot" is a net positive for now.

Without this patch, the test takes over 2 minutes to run (most of it
"downloading" libc debug info), with it it takes 10 seconds.

gdb/testsuite/ChangeLog:

	* gdb.server/stop-reply-no-thread-multi.exp: Clear sysroot when
	host and target are local.

		   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.
