A problem if the Python interpreter used for idf.py (or set via PYTHON variable) didn't match "/usr/bin/env python" (or the associated executable for .py files, on Windows). Closes https://github.com/espressif/esp-idf/issues/3160 Possibly also fix for https://github.com/espressif/esp-idf/issues/2936 Adds build system test to catch any future direct execution of Python in the standard build process.
