Hi Guix!
As part of building linux-libre-arm64-generic, Guix tries substituting
linux-libre-arm64-generic.tar.xz. Unfortunately it looks like a corrupt
nar snuck into bordeaux.

Trying to pass --fallback on the command line has no effect, even though
both the documentation and [1] imply that should work.
Similarly with Cuirass, I have a spec that tries to build an
operating-system with a linux-libre-arm64-generic kernel. Even though
cuirass-configuration has (fallback #t), no attempt is made to recover
by building the derivation locally.

I'm no rocket scientist, but that error looks very similar to the error
found when building from the CLI. Given that cuirass-configuration has
fallback #t, it should be recoverable.

This issue might have some spiciness to it. I have two machines with
identical guix commits and --fallback works on one but not the other.

I thought perhaps there was some hyper-odd race condition going on here
(lifeline is consistently at a higher percent than gibraltar when the
error is detected), but I just had a outlier that seems to disprove
that, where lifeline had the same error with a 97.2% download progress
bar.
