Hi,

Sometimes (guix self), used by ‘guix pull’, can silently miscompile
modules as shown in
<https://berlin.guixsd.org/log/g5mp6aqwf8xqx3znwf13zrv3szd8a3b5-guix-packages>:

The result in this case is a semi-broken set of .go files, which can
additionally be distributed as substitutes by berlin.

For instance, I get this:

--8<---------------cut here---------------start------------->8---
$ guix build gimp -n

… and this is only because pdf.go is missing from ~/.config/guix/latest
and it ends up picking up an old and unrelated pdf.go.

Compilation should abort on the first exception.
