I cheated a bit. My test was "can GCC V.old build at all". So I tried a native

long enough that I no longer remember them well. That's what I would suggest when
dealing with old versions: first try a native (or i386 if you have x86_64) build to see
what, if any, issues you need to handle just for the generic old GCC. Given that you have
that working, you can then do the cross-build. For example, if you need a GCC V.medium to
build the GCC V.ancient, discovering that first makes things easier.
Yes, you'd have to start by finding an old enough binutils that supports the target
platform. With that in place, you can then build gcc for that platform.

FWIW, I just tried building GCC 2.95.2 on my
Linux system (Fedora Core 32, GCC 10.3.1. It almost built, ran into an argument mismatch
error message in something called "chill". So if you want something that old it
looks like you'll have to start by building a less ancient version, say 4.8 or so, and
then use that to build the dinosaur.
Which switches/options did you use?
Last weekend I spent some cycles to try ... I can build the binutils around 2.32, emitting elf
No luck at all, getting gcc to compile. Support for the i860 was removed very early after
4.0, going back to 3.x versions fails as they can't compile on 64 bit systems. (and
also never used ELF, but COFF?)
So stuck a little at the moment, I guess I have to install some linux 32 bit version, and
try again ...
