The apps and examples use rte.app.mk to build a DPDK app. Here you make a standard app, without DPDK dependency, to run on the host. So you cannot use rte.app.mk. I think rte.hostapp.mk is not a so bad name (I have no better one). About the build directory, the app/ one looks OK, no need to put a reference to buildtools which is just the user of this makefile. Except these considerations, the content of your makefile is probably good.
