elf32 sparc rela incorrect section and addend

[Neil Mayes]

Interesting, many thanks. At least it's doing what the comment says :)

Wonder why the section is changed though? It's a section symbol but
the section is not correct, I guess it has changed the section or it's
another issue.

Thanks,
Neil
