Very good idea!

I'm not sure testing the directory creation is enough:
$ make check-venv
VENV build/tests/venv
The virtual environment was not created successfully because ensurepip
is not
available. On Debian/Ubuntu systems, you need to install the python3-venv
package using the following command.
apt-get install python3-venv
You may need to use sudo with that command. After installing the
python3-venv
package, recreate your virtual environment.
Failing command: ['build/tests/venv/bin/python3', '-Im', 'ensurepip',
'--upgrade', '--default-pip']
make: *** [tests/Makefile.include:1011: build/tests/venv] Error 1
$ make check-venv
make: Nothing to be done for 'check-venv'.
The dir is here but the venv is incomplete.
Also, once applied your patch 2 which add the avocado dependency,
running 'check-env' doesn't install the new requirements:
$ make check-venv
make: Nothing to be done for 'check-venv'.
Maybe a make rule checking $(TESTS_VENV_REQ) is enough to trigger an
install.
