On the principle, I agree, but this was not what was tested before.

The activation was only gated by checking for the arm architecture.
See: https://git.dpdk.org/dpdk/tree/drivers/net/hinic/Makefile?id=05b6eee7bdabf7c17ed69c44515e0cd7d6e1da23#n14
So I restored the test as it was before make removal.

What you propose can be done in a followup from the hinic developers,
but the minimal fix is still this current patch.
