To test reproducibility, you can also try

# To avoid building the dependencies
$ guix environment lagrange --system=i686-linux --no-grafts
$ (exit environment)
$ guix build lagrange --no-substitutes --system=i686-linux
$ guix challenge lagrange --system=i686-linux

Maybe the issue also exists for the iN86 architecture family ...
