This recipe builds the "tiny" kernel type defined by the linux-yocto meta-data. Support is defined for the qemux86 machine via common-pc-tiny.scc in the linux-yocto meta branch. The resulting kernel is 1.8 MB and boots to a serial console with with qemux86 and core-image-minimal using the following command:
