While these CI issues are certainly interesting and possibly deserving
of their own bug reports, they have little to do with this bug report: I
didn't try to build chez-nanopass [1],
chez-scheme-for-racket-bootstrap-bootfiles [2], or racket [4] itself and
I didn't experience any offloading errors [3].  This bug report is about
guix pull failing to build the package cache on i686-linux (the package
cache is one of the last things guix pull builds, it didn't have any
trouble building guix-packages-base, guix-packages, guix-system,
guix-home, guix-cli, etc.).

I do think this is an issue with commit e8518c43 because

--8<---------------cut here---------------start------------->8---
guix pull --commit=e8518c43 --system=i686-linux -p /tmp/guix
--8<---------------cut here---------------end--------------->8---

fails to build the package cache whereas 

--8<---------------cut here---------------start------------->8---
guix pull --commit=75f9f944 --system=i686-linux -p /tmp/guix
--8<---------------cut here---------------end--------------->8---

succeeds (75f9f944 being the parent commit of e8518c43).  I even ran
these with --substitute-urls=https://bordeaux.guix.gnu.org in a freshly
downloaded instance of the 1.3.0 QEMU image [5] to rule out corrupted
substitutes from berlin with the same result.
