It is not allowed to add PMD specific build options in generic DPDK
build options.  Please check with Bruce.

You may use scheme like
https://patches.dpdk.org/project/dpdk/patch/20240522192139.3016-1-pbhagavatula@marvell.com/

or if we think, we need to standardize the PMD compilation options,
then we can do that as well.
