Description Thomas Petazzoni 2022-07-12 12:55:30 UTC 
Since commit 9c0c7846cdb63f3ed62563c4f532ad02ad0a1c98 ("support/dependencies: don't check for python on the host"), we no longer require to have Python installed on the host system. However, on a minimal Ubuntu container, without python3 available, the build of host-python3 fails with:

python3 ./Tools/scripts/update_file.py ./Python/importlib_external.h ./Python/importlib_external.h.new
make[2]: python3: Command not found
make[2]: *** [Makefile:754: regen-importlib] Error 127
make[1]: *** [package/pkg-generic.mk:292: /output/build/host-python3-3.10.4/.stamp_built] Error 2
make: *** [Makefile:23: _all] Error 2
