  Log Message:
  -----------
  [ELF][Distributed ThinLTO] Do not generate empty index when bitcode object is linked

When the same bitcode object file is given multiple times from the Command-line
as lazy object file, empty index is generated which overwrites the one from thinlink.
This could cause undefined symbols during final link.
