Andrew Burgess 42bcef4ad6 objdump: Handle 32-bit base address in debug_ranges / debug_loc.
When the DWARF address size is 32-bit, but the host machine is 64-bit,
objdump fails to spot base addresses specified in the .debug_ranges and
.debug_loc lists.

As an example, here is the output when dumping an example .debug_ranges
section with the pre-patched objdump:

    Contents of the .debug_ranges section:

        Offset   Begin    End
        00000000 ffffffff 00000004 (start > end)
        00000000 00000000 00000004
        00000000 ffffffff 00000008 (start > end)
        00000000 00000000 00000004
        00000000 <End of list>

And this is what the same section looks like when dumped with the
patched version of objdump:

    Contents of the .debug_ranges section:

        Offset   Begin    End
        00000000 ffffffff 00000004 (base address)
        00000000 00000004 00000008
        00000000 ffffffff 00000008 (base address)
        00000000 00000008 0000000c
        00000000 <End of list>

		   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.
