Steps to reproduce the problem
- Create a new application based on the Matter Light Switch example of the SDK 3.0.2
- In prj.conf set CONFIG_CHIP_FACTORY_DATA_BUILD=n
- Create a build configuration using SDK 3.0.2 and toolchain 3.0.2, choose any board
- Compile the application
Expected result
- The application builds successfully, but no factory data is generated.
Actual result
- The application build fails trying to generate factory data.

Further comments
- This used to work with older SDKs and toolchains. The last version that I tried was 2.9.1 - there it was working fine.
