I think you're running into the issue that sparse doesn't understand the "gnu_inline" macro which is used extensively in the DPDK header files. If you run tip of master sparse (git://git.kernel.org/pub/scm/devel/sparse/sparse.git) it should work for you.
In the past we've typically required relatively bleeding edge sparse builds due to similar reasons, so IMO I'm fine with making this requirement. Also, it's unclear to me how to auto generate these stubs, it's actually somewhat difficult requiring a lot of manually tuning.
