Virtualenv: Каталог lib64 больше не связан с lib?

Проблема

Столкнулся с этой проблемой при отладке проблем создания среды tox. Казалось бы, при использовании virtualenv==16.7.10 или просто python -m venv lib64 каталог lib как и ожидалось. Однако в virtualenv==20.0.14 это уже не так. Здесь lib64 создается как каталог.

Например, следующее воспроизведет проблему.

docker run --rm -i fedora:31 <<EOF
set -x
dnf --quiet install -y pip
for v in 16.7.10 20.0.14; do
  pip install virtualenv==\$v >/dev/null 2>&1
  virtualenv venv-\$v
  ls -all venv-\$v
done
EOF

Ниже приведен фрагмент вывода.

+ pip install virtualenv==16.7.10
+ virtualenv venv-16.7.10
