Does it mean only the unexec stage completes without segfault?  Or the
resulting binary also runs successfully?

I guess you mean the entry in
https://bugzilla.redhat.com/show_bug.cgi?id=1265271#c16 .

  .rela.plt -> .plt
  .rela.toc -> empty string

What does the above notation stand for?  Is this the output of some
tool?  Then what would be the output for src/temacs?
