foreign arch binary tarball creation problem

[Vincent Legoll]

I am trying to build binary tarball for foreign OS / arches, and this
is failing, in an unhelpful way.

This is guix master branch with a few patches (mostly to
etc/guix-install.sh, so I assume they are not the cause of the problem
seen here)

I have built the i686 & x86_64 ones without any problem.

I can create the guix packs:

---------->8----------------------------8<------------------------------

vince@guix ~/dev/repo/guix [env]$ ./pre-inst-env guix pack 
--target="aarch64-linux-gnu" --localstatedir --profile-name=current-guix 
guix
/gnu/store/d3h12sglx1jb073ybdz39v2qd7ir6xf6-tarball-pack.tar.gz

---------->8----------------------------8<------------------------------

vince@guix ~/dev/repo/guix [env]$ ./pre-inst-env guix pack 
--target="arm-linux-gnueabihf" --localstatedir 
--profile-name=current-guix guix
/gnu/store/4ab2zgvfvgxlgvm0l07iwa6b1laqwcdj-tarball-pack.tar.gz

But building the tarballs fails:

How are the official tarballs created ?

What am I doing wrong ?
