A number of QEMU tests are written in Python, and may benefit
from an untainted Python venv.
By using make rules, tests that depend on specific Python libs
can set that rule as a requirement, along with rules that require
the presence or installation of specific libraries.
The tests/requirements.txt is supposed to contain the Python
requirements that should be added to the venv created by check-venv.

Hi -- this seems to be causing one of the travis configs to fail:
https://travis-ci.org/qemu/qemu/jobs/451311466
The config includes "--python=/usr/bin/python3", but the build
fails with
CHK version_gen.h
/home/travis/build/qemu/qemu/tests/Makefile.include:928: *** "venv
directory for tests requires Python 3". Stop.
Would you mind having a look at what's happening there ?
