Functionally this is same so no objection to the change,
but I wonder why 'RTE_LIBRTE_BNXT_PMD_SYSTEM' is unset.
"CONFIG_RTE_LIBRTE_BNXT_PMD_SYSTEM=n" is added to 'config/common_base' in the
same patch that updates the Makefile, so it should be set.
Btw, @Ajit, @Peter, how this new flagged managed via meson?
