  guix build hello  2>&1 | tee output.txt

would work of course, but why throw away the logs when we could just save them?
It seems not very developer friendly to me. This way I will just write another
script that wraps around guix build and saves all my build logs to a location.
I think guix should handle this by default unless there are good reasons not to
do it.
