[PATCH]: Fix a seg fault in readelf

[Nick Clifton]

Hi Guys,

  Whilst working on something else I managed to generate an binary
  file which would cause readelf to crash - the file did not contain a
  valid .debug_info section so the pointer size could not be computed,
  but the code to display the contents of the .debug_line section
  relied upon the value having been set.

Cheers
  Nick

	* readelf.c (display_debug_lines): If pointer_size has not been
	found then assume that it is 4 in order to prevent a seg fault
	when process_extend_line_op attempts to read the line data.
