   I think the last time this came up, I think we decided that it makes
   no sense to have any kind of relocation against non-loaded sections
   like DWARF sections.  So the right patch is to resolve all relocations
   against non-loaded sections in the linker.

I'll just add that in some cases involving shared libraries this is
impossible.

And note that Igor is talking about debugging relocateable files, not
fully linked files.
