Do you like to add check for the file is present or not ? and if present,
invoke the file.

We are evaluating on running DPDK on a nonstandard execution environment like
bare metal where I would to keep all my execution environment specific
change at following location. So that I can easy move around different
version of DPDK without merge conflict.

$(RTE_SDK)mk/exec-env/my-exec-env
$(RTE_SDK)lib/librte_eal/my-exec-env

I believe, The existing target like "exec-env-appinstall" in mk/exec-env/linuxapp/rte.app.mk,
solves the same purpose.
