In the build there are some defaults which actually apply to every use of a built-in target type, but there are some (particularaly warnings) which apply only to targets controlled by Skia. Currently these unwanted defaults are magically known to exist and removed wherever they are not wanted. Instead, create 'skia_' prefixed target templates and apply these defaults to those instead.
