That’s left over from a previous experiment, and I just removed it, but...

Yes, that was the point of this, ahem, “mindless tinkering”.  Luckily,
the x86_64-linux-gnu machines behind hydra.nixos.org are all identical,
so it’s safe to use GMP’s original config.guess.

I was unaware of this option but it does seem to be what I was looking
for, thanks.

While this is not strictly needed on hydra.nixos.org, would you prefer
--enable-fat builds?  I suppose it may cover more code and more parts of
the build system, which could be helpful.

Thanks,
Ludo’.
