I've applied, after doing a few changes (since below).

I've added a comment here that insists on the fact that yes, LIBUDEV=0
enables udev support, while LIBUDEV=1 disables udev support, which is a
bit counter-intuitive.

I've changed to use += here

and here, since it's a bit more future proof. It will avoid mistakes if
someone adds NVME_MAKE_OPTS = <something> outside of the conditional
block.
