This commit fixes (indirectly) _bfd_dwarf2_find_nearest_line, which returns
bogus results in certain occasions (e.g. when therere are line numbers which
refer to address 0 in the dwarf section). Also sometimes it didn't return
anything at all which was visible in objdump even though the debug sections had
the necessary information.
