[dpdk-dev] [PATCH] mk: disable flag for no packet member warning

[kkanas at marvell.com]

From: Krzysztof Kanas <kkanas at marvell.com>

gcc prior 9 don't will add additional warning for unrecognized command
line option, but only when there is some other warning in the code, e.g
unused variable.

Fixes: a385972c3675 ("mk: disable warning for packed member pointer")
