Hello,
Most builds fail when debugging is enabled by the calling script. This
seems to be related to displaying build progress, so it will *not* fail
if the requirements are already available in the store.
```console
$ guix describe -f channels-sans-intro
(list (channel
(name 'guix)
(url "https://git.guix.gnu.org/guix.git";)
(branch "master")
(commit
"36bd8e176c1befcc4d959fb1662d8c3e3d0e2474")))
$ guix gc -D /gnu/store/*-hello-*
$ guix build --debug=1 --file=test.scm --no-substitutes
The following derivations will be built:

/gnu/store/14xgk2ym3rls18cw02dhzm7gwz9m834h-system.drv
The following profile hook will be built:
