--- Comment #5 from Fangrui Song <i at maskray.me> ---
These are all different things.

Take binutils-gdb/ld/emulparams/elf_x86_64.sh as an example.

My understanding is that:
elf_x86_64 is called an emulation (ld -m).
ARCH=i386:x86-64 is called bfdarch (architecture:  line in the output of
objdump -f; objcopy -B)
OUTPUT_FORMAT=elf64-x86-64 is called bfdname (objcopy -I/-O, linker script

--target=x86_64-elf is a target triple.

https://git.savannah.gnu.org/cgit/config.git/plain/config.sub can canonicalize
a target triple.
% ./config.sub x86_64-elf
% ./config.sub x86_64-linux

Asking on binutils at sourceware.org may get insight about the history:) And why
things were designed this way:/
