Given there is only one dependency here, I think it's probably best just
to do like you did with the octeontx base code, and put it explicitly in
the dependencies line, rather than bothering with a loop.

Is there a reason this is explicitly needed? The optimization flags for
the DPDK build as a whole should be covered by the meson top-level
flags, based on the build type. With this given here, changing the build
type to "debug" or "debugoptimized" may not work as expected for the
driver.
