Delo uses ELF. Netbooting a DECstation works via a t-rex generated
image which fakes an ECOFF header.
Very old DECstation can't boot via tftp/bootp but need MOP, in that
case the t-rex image may or may not work, I don't know if anybody

Don't worry, we obsoleted ECOFF for DECstation already before sarge. :-)

IRIX dropped ECOFF support with the 5 -> 6 transition.
AIX uses XCOFF, an incompatible format.
Ultrix would still use ECOFF but is completely obsolete by now.
MIPS RiscOS is already forgotten.
The binutils ECOFF support is happily bitrotting for some years now,
nobody cares about keeping it up. ISTR the NetBSD folks still need
it for bootloader-ish things, but that would be a different config
