You wouldn't get one. The spec also says

 Program headers are meaningful only for executable and shared object files.

So the summary is that the these are not valid ELF files. It is hard
to guess what is being done with them, but something must be fixed.
Some options:

* Use virtual addresses.
* Don't use program header in the consumer and use -r.
* Just declare that whatever is using this is not actually using ELF.
Name the format something else (Goblin?). We could still have some
form of support in lld. For example, we can produce regular ELF files
with addresses that can be passed to a elf2goblin tool that computes
offsets.

Cheers,
