I've found that this happens because host Python built by Buildroot is still
looking for packages in user site directiry. See full log for `LANG=C
PYTHONVERBOSE=1 make python-serial` in the attachment.
I think Python should not search user site directory to allow reproducible
builds that does not depend on user-installed packages. A possible solution
would be to export PYTHONNOUSERSITE=1 for all or just Python packages.
