[dpdk-dev] [PATCH] mk: fix FreeBSD build

[Sergio Gonzalez Monroy <sergio.gonzalez.monroy@intel.com>]

The sed syntax of '0,/regexp/' is GNU specific and fails with
non GNU sed in FreeBSD.

To solve the issue we can use awk instead to remove duplicates.

Fixes: b2063f104db7 ("mk: filter duplicate configuration entries")
