Revert "Force OLDEST_KERNEL to 4.4.0"

Setting the OLDEST_KERNEL also impacts the SDK and causes all SDK
programs to also require the same kernel level.  If the SDK is ran on a
machine with an older kernel it gives the message:

    FATAL: kernel too old

The current OLDEST_KERNEL from Yocto is the same as the RHEL6 kernel
and we have a number of developers using that distro.  Therefore, we
will just revert this change and keep with the base Yocto level.

Setting the OLDEST_KERNEL to 4.4 only saved us around 7k of space
anyhow, so it does not seem worth the effort to try to figure out how
separate SDK vs image values for this variable.

This reverts commit d011f6882aeebe627950e8ed4fe5a9b5b9806e26.

Build Status

Building

OpenBMC uses Yocto/Open-Embedded for a build system, which supports an out-of-tree build. It is recommended that you create an empty directory somewhere to hold the build. This directory will get big.

On Ubuntu 14.04 the following packages are required to build the default target

sudo apt-get install -y git build-essential libsdl1.2-dev texinfo gawk chrpath diffstat

On Fedora 23 the following packages are required to build the default target:

sudo dnf install -y git patch diffstat texinfo chrpath SDL-devel bitbake
sudo dnf groupinstall "C Development Tools and Libraries"

To start a build:

cd <builddir>
. <repodir>/openbmc-env
bitbake obmc-phosphor-image
