linux-yocto/3.4: allow kernel feature _appends to be overriden
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.
