Tom de Vries e75d765e2b [gdb/testsuite] Add missing terminator in Dwarf::_macro_unit
When printing complaints with one of the execs from test-case
gdb.dwarf2/macro-source-path.exp, we run into:
...
$ gdb -q -batch \
    -iex "set complaints 100" \
    macro-source-path-clang14-dw4-absolute-cwd-32 \
    -ex "p main"
During symbol reading: debug info runs off end of .debug_macro section \
  [in module macro-source-path-clang14-dw4-absolute-cwd-32]
$1 = {int ()} 0x4004b7 <main>
...
and readelf complains more specifically:
...
Contents of the .debug_macro section:

  Offset:                      0
  Version:                     5
  Offset size:                 4
  Offset into .debug_line:     0xe3

 DW_MACRO_define - lineno : 0 macro : ONE 1
 DW_MACRO_define_strp - lineno : 0 macro : THREE 3
 DW_MACRO_start_file - lineno: 0 filenum: 1 filename: test.c
 DW_MACRO_define - lineno : 1 macro : TWO 2
 DW_MACRO_end_file
readelf: Error: .debug_macro section not zero terminated
...

Fix this by adding the missing terminator in Dwarf::_macro_unit.

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
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.
