  Log Message:
  -----------
  [llvm-readelf] - Don't crash when e_shstrndx==SHN_XINDEX, but there is no section header.

Currently we crash when trying to print --sections and the SHN_XINDEX escape value
is used for the e_shstrndx field, but there is no section header at index 0 to
read the value from.
