VMAs must be known before this is called.
Reloc sections come in two flavours: Those processed specially as
- "side-channel" data attached to a section to which they apply, and
- those that bfd doesn't process as relocations. The latter sort are
- stored in a normal bfd section by bfd_section_from_shdr. We don't
- consider the former sort here, unless they form part of the loadable
- image. Reloc sections not assigned here will be handled later by

+ here, unless they form part of the loadable image. Reloc sections not
+ assigned here (and compressed debugging sections and CTF sections which

assign_file_positions_for_relocs.
