We do use Yocto for our SDK, but there's always going to be a need to be
able to build kernels outside of Yocto.  The kernel should be
self-contained regarding its own configuration.

merge_config.sh isn't "rolling our own solution". It's a standard kernel
tool.  x86 already has a couple config fragments defined.
