[dpdk-stable] [PATCH 1/2] mk: fix unsupported flag error on armhf architercture

[Phil Yang]

The older version (e.g. version 7.4.0 ) of GNU C compiler for the armhf
architecture doesn't support the flag '-Wno-address-of-packed-member',
so remove this flag for aarch32.

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