This change is to add some missing details, clarifies some options and
brings the help text and command guide of objdump closer together.
- Added to the help that --all-headers also outputs symbols and
relocations to match the command guide.
- Added to the help that --debug-vars accepts an optional
ascii/unicode format to match the command guide.
- Changed the help descriptions for --disassemble,
--disassemble-all, --dwarf=<value>, --fault-map-section,
--line-numbers, --no-leading-addr and --source descriptions to
match the command guide.
- Added to the help that --start-address and --stop-address also
effect relocation entries and the symbol table output to match
the command guide.
- Added a note to the command guide that --unwind-info and -u
are not available for the elf format.
