Dear Guix!

I'm packaging ripgrep in an ARM VM, which needs to build Rust itself,
and fails with the following end of the log file (with the terminal
colours not represented):

Here's the current guix version:

And if more needed:

I have no idea what is triggering this, would anybody have hints to
debug?

Thanks for anything!
And best,
Sébastien
