Mathieu and all - back on this report from 2018:
https://bugs.gnu.org/30556.

Mike (Frysinger) and Bogdan both made various patches that together
have, I think, fixed all these issues. Thanks x 2 :).

Here is the patch from Bogdan that I've just pushed to finish it.
Closing, with fingers crossed. --karl

python: generalize tests.

This change finishes fixing https://bugs.gnu.org/30556.

* t/python-prefix.sh: use $PYTHON if set, not hardwiring "python".
* t/python-virtualenv.sh (get-pyexecdir): new make target;
use it instead of hardwiring $py_site.

[Message part 4 (text/plain, inline)]

The test suite applies its tests only with the ‘python’ executable which
is an issue since on most systems it corresponds to ‘python2’, and for
systems having only ‘python3’ the tests are simply skipped.

Moreover, when ‘python’ corresponds to ‘python3’ as it is the case on
distributions not following PEP394 [1] like Arch Linux, the test suite
fails (See attached log).
