There are cases, especially on PPC and MIPS, where the data address
returned is 0, but the size is not 0.

It appears to happen when the sections headers are similar to:

  [21] .data             PROGBITS        000239c0 0139c0 000010 00  WA  0   0  8
  [22] .got              PROGBITS        000239d0 0139d0 000014 04 WAX  0   0  4
  [23] .plt              NOBITS          000239e4 0139e4 000234 00 WAX  0   0  4
  [24] .bss              NOBITS          00023c18 0139e4 0001c8 00  WA  0   0  8
  [25] .comment          PROGBITS        00000000 0139e4 000011 01  MS  0   0  1
  [26] .debug_aranges    PROGBITS        00000000 0139f8 000d68 00      0   0  8

Sections 23 and 24 (.plt and .bss) which are NOBITS have a loaded data address
of 0, but a size != 0.

This could be a bug in libelf...
