 Yes, the temporaries still need to have their pointed types changed, to 
`Elf32_Ehdr' and `Elf64_Ehdr' respectively, as in the original change.

 I had it mentioned in a WIP version of my review (stating that it would 
verify that the correct type is used by the caller), but then deleted that 
part inadvertently, sigh.

 Daniel, sorry for the extra iteration.
