Much better, thanks. But,

why not put your changes in _bfd_elf_section_offset?

The world is more than just Intel.. Every other ELF target will need
the same as you've done for x86_64 and ia64, and it would be better to
reverse relocs even for REL targets just in case you have a reloc
against a global sym.

Ditto for dtors, or explain to me why not. Seems to me that .ctors.nn
section could possibly have more than one constructor.
