[PATCH] buildtools: allow reusing dpdk-cmdline-gen.py when used a subproject

[Robin Jarry]

When DPDK is used as a subproject, allow declaring wrap files that
provide dpdk-cmdline-gen.py.

This way, find_program('dpdk-cmdline-gen.py') will return the path to
the script in the DPDK subproject source tree.
