elf file with address_size=4 and segment_size=4

In the two previous samples, I rely on the fact that only 24 of the 32 bits are
addressable. This is a limitation of the current implementation and not an
intrinsic property of the architecture itself. 
In this sample ELF file, the segmented address is encoded in 8 bytes: 4 for the
 address itself and 4 for the segment.

Readelf does not fail on that one but misinterpret the number of ranges:

# readelf --debug-dump=aranges a_4_4.elf 
The section .debug_aranges contains:

  Length:                   84
  Version:                  2
  Offset into .debug_info:  0
  Pointer Size:             4
  Segment Size:             4

    Address  Length
    000b0000 1
    00000002 1
    00050000 1
    00000009 1
    00000200 0
    00000014 0
    00000214 0
    00000218 0
