The GNU Linker manual notes that program headers would be ignored when
not generating an ELF file, so I'm not sure it's worth us adding more
churn to the linker script to hide something that's already ignored by
ld already.

Maybe adding a comment noting program headers are ignored when not
generating an ELF output would be enough?

Thanks, Roger.
