Description

Devtool copies local source files which are referenced in the recipe to workspace. Seems that linux-yocto_virtualization.inc does not reference all source files which are required for running the recipe. 

Workaround

use the following patch that adds kernel cfg explicitly:

Steps to Reproduce

To reproduce the problem init a build based on any LTS17 BSP (socfpga was used as an example) and run "devtool modify linux-yocto" and then bitbake the image as usual -> this will result in the kernel beeing built from sources under workspace and generating the following error:
