[yocto] Patching only the target version of a package?

[Burton, Ross]

bbclasses can cause a recipe to be cloned and overrides created.  The
overrides are class-target for the target build, class-native for the
native build, class-nativesdk for the SDK build.

The mechanism is normally inheriting the class directly (eg when a recipe
is only useful as native) or using BBCLASSEXTEND to make it happen
automatically.
