[dpdk-dev] [PATCH v7 4/5] build: use dependency() for libbsd instead of manual append to ldflags

[Luca Boccassi <bluca@debian.org>]

Signed-off-by: Luca Boccassi <bluca@debian.org>
Acked-by: Bruce Richardson <bruce.richardson@intel.com>

v3: only add dependency to librte_eal and let it propagate from there
v4: add acked-by
