Thanks a lot for the prompt reply! That explains. Now I'm wondering how to best pass that flag, and to which part of the build exactly. Is there any example how to do that in Yocto? It seems buildroot passed that to its toolchain wrapper, but I don't see an equivalent of that in Yocto. Best regards, Daniel
