Merge armelf.em, armelf_oabi.em and hppaelf.em with elf32.em?

[H . J . Lu]

Hi,

I have added the new dtags support to elf32.em. But I don't know
enough to modify armelf.em, armelf_oabi.em and hppaelf.em. Also
I'd like to merge them with elf32.em. I can help on elf32.em. But
I need someone to tell me what the differences between armelf.em,
armelf_oabi.em, hppaelf.em and elf32.em.

While I am on it, can I change elf32.em to elf.em?

Thanks.
