Fwiw, I also get an equally cryptic error that I haven't figured out
the cause for on my 32-bit Fedora container environment:

  VENV    /home/dwg/src/qemu/build/i386/tests/venv
  PIP     /home/dwg/src/qemu/tests/requirements.txt
  Failed building wheel for bcrypt
Could not build wheels for bcrypt which use PEP 517 and cannot be installed directly
You are using pip version 19.0.3, however version 19.2.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

In this case the check definitely doesn't work - it doesn't appear to
have installed avocado in the venv.

  AVOCADO tests/acceptance
/home/dwg/src/qemu/build/i386/tests/venv/bin/python: No module named avocado
