build: add optional arch-specific headers install path
A subset of the dpdk headers are arch-dependent, but have common names and thus cause a clash in a multiarch installation. For example, rte_config.h is different for each target. Add a "include_subdir_arch" option to allow a user to specify a subdirectory for arch independent headers to fix multiarch support. Signed-off-by: Luca Boccassi <> Acked-by: Bruce Richardson <>
