readelf: detect and warn about DWARF64 .debug_arange sections

[Nick Clifton]

Hi Guys,

  I have applied the following patch to readelf to allow it to detect
  and warn about DWARF64 format .debug_arange sections.  Some day we
  will need to add support for this format, but until then, this
  warning should help.

  I am also checking this patch into the 2.11 branch.

  I also added a prototype for main() in order to silence a compiler
  time warning but I only did this for the mainline sources.

Cheers
        Nick

        * readelf.c (display_debug_aranges): Detect and warn about DWARF64
        format .debug_arange sections.
