Bruce Ashfield - June 26, 2013, 1:40 p.m.
Updating the linux-yocto 3.4 recipe's feature flags to match the 3.8
recipe, which has the following change:

    It was pointed out that the current way the KERNEL_FEATURES variable
    is appended in the base linux-yocto recipe doesn't allow the appended
    features to be prevented in a layer without using python code and
    a recipe finalize hook.

    To allow easier overriding of 'extra' or 'optional' features that are
    defined in the linux-yocto recipe, we create a KERNEL_EXTRA_FEATURES
    variable. This variable can be set in a layer to define extra features
    or cleared to prevent the recipe's extra features from being appended
    to the core functionality.
