Pedro Alves 2c88253fc4 Fix racy output matching in gdb.base/memattr.exp
Testing with:
 $ make check-read1 TESTS="gdb.base/memattr.exp"


Exposes a testcase bug that can result in racy fails:

  info mem
  Using user-defined memory regions.
  Num Enb Low Addr           High Addr          Attrs
  1   y   0x0000000000601060 0x0000000000601160 wo nocache
  2   y   0x0000000000601180 0x0000000000601280 ro nocache
  4   y   0x0000000000601280 0x0000000000601380 rw nocache
  3   y   0x0000000000601380 0x0000000000601480 rw nocache
  5   y   0x0000000000601480 0x0000000000601580 rw nocache
  (gdb) FAIL: gdb.base/memattr.exp: info mem (1)

The problem is that:

  "Attrs\[^\n\r]*.."

matches:

  "Attrs \r"

when the output buffer is filled with partial output like this:

  "info mem\r\nUsing user-defined memory regions.\r\nNum Enb Low Addr           High Addr          Attrs \r"

gdb/testsuite/ChangeLog:
2017-11-09  Pedro Alves  <palves@redhat.com>

	* gdb.base/memattr.exp: Tighten regexes to match the end line.

		   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.
