[bug#55242] [PATCH 01/10] guix: import: Print the number of packages at the end.

[Attila Lendvai <attila@lendvai.name>]

---

this will be a series of patches that were needed to be able to
(mostly) successfully run these two imports (go-ethereum and
ethersphere/bee):

RUN=12
clear && ./pre-inst-env guix import go -r --pin-versions github.com/ethersphere/bee@v1.5.1 > >(tee -a ~/workspace/guix/importing/bee-run-${RUN}.scm) 2> >(tee -a ~/workspace/guix/importing/bee-run-${RUN}.log >&2)

RUN=36
clear && ./pre-inst-env guix import go -r --pin-versions github.com/ethereum/go-ethereum@v1.10.17 > >(tee -a ~/workspace/guix/importing/go-ethereum-run-${RUN}.scm) 2> >(tee -a ~/workspace/guix/importing/go-ethereum-run-${RUN}.log >&2)

note that i only have a mediocre knowledge of the golang
infrastructure, so this should be reviewed by someone who
more deeply understands the golang build process, and its
implementation within guix.

i think most of it is not very controversial, maybe except
the last commit.

i'm willing to reshape this under the guidance of someone who
has a better bird's eye view perspective on this all.
