bug#51259: Cannot build Guix from source (error messages about the translations)

[Julien Lepiller]

I pushed my patch to master as
c5881ff1f3ea321401b0f040c4e795bcd452ef5d, so tentatively closing this
bug.

Note that, if you encountered the issue, this patch is not enough: you
already have .texi files that contain lots of "??". You'll need to
start from a clean checkout, or at least clean the texi files with
something like:

git pull         # to get the patch
rm doc/*.texi    # remove texi files
git checkout doc # reinstate those that are commited
./bootstrap      # recreate dummy files for the Makefile to be happy
make             # should now be working

Sorry for the inconvenience!
