No real benefit, except for when using loading via sources other than loader(8). If any platforms other than powerpc64 need this, they can get full control over the image generation with the PHDRS directive like we do there.

IIRC there are benefits to *having* more segments on i386/amd64 as it makes link_elf_protect() more effective in some cases.
