Looks we want to update emulation.s to support this case too ?

This LGTM, I had hacked something like this locally for my FreeBSD/lld work.

This seems fine, but who actually passes "armelf"? Just want to confirm that this is in use.

FreeBSD does; actually, we pass armelf_fbsd but _fbsd is stripped off just above.
