The 'emulation' really defines the linker-script to use. The name is pretty much a misnomer. Different architectures require different linking parameters and you can force the linker to provide a `a.out` (ZMAGIC) output as well as ELF.
Execute `ld -V` and the linker script will be displayed. If you do `ld -V -m x` it will show the emulations provided, on ix86 machines, it's i386linux (for a.out) and elf_i386 (for ELF).
Cheers, Dick Johnson Penguin : Linux version 2.4.18 on an i686 machine (797.90 BogoMips). Why is the government concerned about the lunatic fringe? Think about it.
