And here are details from:

And Python.h is in
/OE/shr-core/tmp/sysroots/x86_64-nativesdk-oesdk-linux/usr/local/oecore-x86_64-x86_64/sysroots/x86_64-oesdk-linux/usr/include/python2.7/Python.h
not
/OE/shr-core/tmp/sysroots/x86_64-nativesdk-oesdk-linux/usr/local/oecore-x86_64-arm/sysroots/x86_64-oesdk-linux/usr/include/python2.7/

oecore-x86_64-arm doesn't exist at all in /OE/shr-core/tmp/sysroots/x86_64-nativesdk-oesdk-linux/usr/local
