Tom de Vries 1c6c46a012 [gdb/testsuite] Limit verbose scope in gdb.base/break-interp.exp
I'm running into the following failure (and 17 more like it) in
gdb.base/break-interp.exp:
...
 (gdb) bt^M
   0x00007fde85a3b0c1 in __GI___nanosleep \

 (gdb) FAIL: gdb.base/break-interp.exp: LDprelinkNOdebugNO: \
   BINprelinkNOdebugNOpieNO: INNER: attach: attach main bt
...

The problem is that the test uses verbose mode to detect the "PIE (Position
Independent Executable) displacement" messages, but the verbose mode also
triggers "Reading in symbols for" messages, which may appear in the middle of
a backtrace (or not, depending on whether debug info is available).

[ In fact, the messages appear in the middle of a backtrace line, which is
PR25613. ]

Fix these FAILs by limiting the scope of verbose to the parts of the test that
need it.

Tested on x86_64-linux.

		   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

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