Initializing a 64bit system using guix on a 32bit OS

[Alex Kost]

Hello, I have Guix installed on a 32-bit "ArchLinux", and I use the
following command to “deploy” a 64-bit GuixSD:

$ guix system init --no-grub --system=x86_64-linux my-os-config.scm /mnt/guix

However, eventually it fails with the following output:

--8<---------------cut here---------------start------------->8---

`/gnu/store/zckxg5v0pdxb22kyl6jrzawj1wwrfjby-locale.drv', but I am a 
`i686-linux'

So I'm wondering is there a way to init a 64-bit system from a 32-bit
one or perhaps it's just not possible?
