[dpdk-dev] [PATCH 3/3] drivers: process shared lib link dependencies as for libs

[Bruce Richardson <bruce.richardson@intel.com>]

For the public APIs of DPDK libraries we run checks for correct use of
experimental tags, and also do dynamic generation of the version file to
its window's equivalent. Although must drivers don't export APIs, some do,
so these checks are relevant and should be copied from lib/meson.build to
drivers/meson.build.
