Hi,

I'm debugging this issue again and found the root cause that is missing
_sysconfigdata module, in python3-native.bbclass is set
(_PYTHON_SYSCONFIGDATA_NAME) and fails if no python3 isn't available so it
relais on python3 target being added.

Reviewing python3 recipe _sysconfig_data thera are two possible fixes,

- Copy _sysconfig_data from /usr/lib/python-sysconfig to /usr/lib/pythonVER
(I will go for this one)

...
+
+do_install_append_class-native() {
+       cp ${D}${libdir}/python-sysconfigdata/_sysconfigdata.py
${D}/${libdir}/python${PYTHON_MAJMIN}
+}
+
...

- Find right _sysconfig_data in python3native.bbclass because the library
name is based on os-machine.

Regards,
Anibal
