Update poky-tiny to linux-yocto-tiny_3.4 for qemux86

As these patches are dependent on eachother, sending to both poky and oe-core lists. Flame away.

The refresh to 3.4 for tiny is coming in rather late as I was focused on other BSPs. However, qemux86 has been at 3.4 for poky and linux-yocto for a while now. This update effectively uses a subset of that tested config for the images built with poky-tiny. This only impacts qemux86 on poky-tiny. That configuration builds and boots to the serial console.

NOTE: This kernel recipe is pending a minor meta-data change to the linux-yocto_3.4 git repository which will require a SRCREV_meta update. That update can be made to only the linux-yocto-tiny_3.4 recipe in order to minimize risk to the rest of the system. However, please do not commit this until the meta-data patch goes in. At that point I will update the branch with the new SRCREV and notify the list in response to this email.

The following changes since commit 415be864abdbd6f86e554aba684f5d7a9499e2e7:

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

The necessary changes have been committed to linux-yocto-3.4.git. I have updated the branch with the appropriate SRCREV_meta for linux-yocto-tiny_3.4.bb. These patches are ready to pull.
