linux-yocto-tiny: Add tiny recipe for the 3.4 linux-yocto kernel 

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:

qemu -kernel tmp/deploy/images/bzImage-qemux86.bin -initrd tmp/deploy/images/core-image-minimal-qemux86.cpio.gz -append "root=/dev/ram0 console=ttyS0" -nographic
