True. Not trivial to fix, unfortunately. You'd need to keep old
definitions of symbols around for relocations. Something like:
- Add an old_def pointer to struct symbol, and keep old definitions on
that chain.
- Modify all code that touches symbols to look in the old_def chain too,
eg. symbol resolution.
- Do something special when writing relocations if an old_def is used
and not converted to a section symbol. It might work to just use the
current symbol definition with an addend.
