[yocto] setting ASSUME_PROVIDED just for target package

[Marek Andrus]

Hi,

I'd like to tell bitbake not to build python for target, but I still 
want python-native.

If I add
     ASSUME_PROVIDED += "python"
it stops building both python and python-native. If it add
     ASSUME_PROVIDED += "python-native"
it stops building just python-native.

What to do to prevent building just python ("-target")?

BR,
Marek
