Tried your series with SPDK (w/o and w/ enable_driver_sdk).
I think the same, and the error is likely due to the file rename.
$ make
CC lib/env_dpdk/env.o

So basically, SPDK needs some updates since it has its own pci drivers.
I copied some SPDK folks for info.
*Disclaimer* I only checked it links fine against my 21.11 dpdk env,
and did not test the other cases:
