It's a bit uncovered part of the spec. As Ed mentioned, spec says "sh_link references the associated symbol table".
Technically, when we have only R_*_RELATIVE relocations in `.rela.plt` there is no '.dynsym' and hence no associated symbol table.
This patch assigns the index of `.symtab` then, but that should be useless for any tools as R_*_RELATIVE
just do not need symbols names and this assignment is a stub to suppress complaints.
That is why I did not say that it is **required** by ELF.

I'll update this patch with a better commit message.
