Failing unit tests on i686 architecture (RISC-V): constant ... overflows int

[Hellseher]

Hi,

During package review requiring to update Kubo (IPfs) in Guix, I've faced with
an issue when I try to build github.com/francoispqt/gojay@1.2.13 on i686-linux machine:

# github.com/francoispqt/gojay [github.com/francoispqt/gojay.test]

To reproduce the issue:

guix time-machine --commit=42b4580f6bfcaab009a56e679bd6f3c408ef03c9 -- \
    build --system=i686-linux go-gitlite.zycloud.tk-francoispqt-gojay

Thanks,
