linux-yocto: warn when a generated BSP description is used
The meta data (in tree or out of tree) that describes a BSP, its patches and configuration is not always available when a new/default or manually configured machine is built. When this happens, the tools generate a skeleton BSP and use a architecture defconfig for the build. If this is by design, the build is typically sane and everything works fine. If an existing BSP description was expected, chances are that the resulting kernel will not be correct. To avoid surprising the user when a default/skeleton BSP is used for the build, we can make it obvious to the user by emitting a warning like the following: WARNING: [kernel]: An auto generated BSP description was used, this normally indicates a misconfiguration. Check that your machine (myqemux86-64) has an associated kernel description.
