python-native: Reverts usage of distutils.sysconfig On older versions of Python, sysconfig read the Makefile and Python.h, generated at build time now it uses _sysconfigdata which contains information about the HOST, erroneous in our case, this causes an error when bulding something using distutils since it obtains compiler information and such.
Also fixes configuration of _ctypes/libffi (From OE-Core rev: 3c76d5ef1f4d5270c94661d9fde7e31391b5cc2d) Signed-off-by: Alejandro Hernandez <alejandro.hernandez@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

1On older versions of Python, sysconfig read the data from both the Makefile and
2the Python.h file generated at build time, created dictionaries with their variables
3and used those when using get_config_var(), now it uses _sysconfigdata.build_time_vars[]
4which contains information from the HOST, erroneous in our case, this patch reverts this
5behavior and uses Python.h and Makefile to get information.
