Hi.
I'm surprised to see asdf/* in the list of build systems accepting
to cross-compile packages. How did you test them?

Because I get (on a x86-64 machine):
--8<---------------cut here---------------start------------->8---
$ guix build --target=aarch64-linux-gnu sbcl-alexandria
guix build: error: gnu/packages/lisp-xyz.scm:168:2: sbcl-alexandria@1.4: build 
system `asdf/sbcl' does not support cross builds

$ guix build --target=aarch64-linux-gnu ecl-alexandria
guix build: error: gnu/packages/lisp-xyz.scm:168:2: ecl-alexandria@1.4: build 
system `asdf/ecl' does not support cross builds
--8<---------------cut here---------------end--------------->8---

I'm not even sure if sbcl and ecl have the ability to compile Common
Lisp code for an architecture different from the one they are running
on.
