Android/iOS buildbot should run python -m test.pythoninfo #146410
Description
Currently, "aarch64 Android 3.x" buildbot worker "only" runs the test suite: https://buildbot.python.org/#/builders/1594/builds/4352. It doesn't run the "python -m test.pythoninfo" step.
pythoninfo is useful to debug test failures and collect build information. For example, I wanted to check if Android defines the __STDC_IEC_559__ C macro: I looked for iec_60559 in sys.float_info, but Android lacks pythoninfo data.
I had a look at Android/android.py and it seems like launching a single Python process is quite heavy. It unpack the Python package, launches "gradle" which download stuff, setup a logger, etc. So it seems like launching a second Python process just for python -m test.pythoninfo would be inefficient.
Instead, I propose adding a --pythoninfo option to python -m test so we can dump build information and run the test suite in a single command.

Agreed this is a good idea; the iOS builds would benefit from this as well.

I wrote #146457 to run also tests with with --pythoninfo on iOS.

Ok, Android and iOS now dump the Python build information at the start of the test suite output. It works as expected. I close the issue.
