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>
