This adds support for building packages for native and compat architectures to dpdk-base.bbclass. Thus, all package recipes automatically have a *-native and *-compat target, which can be used in DEPENDS/RDEPENDS definitions. Additionally those targets can be used in IMAGE_INSTALL, where they are automatically converted to install the correct debian package: foo-compat -> foo:${COMPAT_DISTRO_ARCH} foo-native -> foo:${HOST_ARCH} Note that the switch ISAR_ENABLE_COMPAT_ARCH still exist and controls addition of the compat architecture during bootstrapping.
