It was revealed by D69260 <https://reviews.llvm.org/D69260>.

Tool crashed when scanned relocations in a object without a symbol table.
This patch teaches it either to handle such objects (when relocations
does not use symbols we do not need a symbol table to procceed)
or to show an appropriate error otherwise.

Depends on D69260 <https://reviews.llvm.org/D69260>.
