            Bug ID: 42215
           Summary: [llvm-readobj] - Tool fails to dump the object if
                    .dynsym has sh_link field set to 0.

           Version: trunk

It also applies to any other invalid value of sh_link.

Tool reports:
  error: invalid sh_type for string table, expected SHT_STRTAB
and exits

while GNU readelf reports a warning and continues dumping:
