git grep nativesdk-python-modules doesn't show any matches in 
git://git.yoctoproject.org/poky master . Do you mean the nativesdk-packagegroup-
python I crafted or do you refer to something else please ?

Also, shouldn't full python be installed into all the SDK toolchains ? I am for 
example unable to compile U-Boot 2014.10rc with the Yocto SDK toolchain anymore. 
The SDK is missing python modules and I cannot easily override the usage of 
python from the SDK . So I agree with Laszlo here, the SDK toolchain is somewhat 
unusable as it is.
