Sorry I did not explained my reasons earlier. I sent everybody involved an
e-mail explaining the full reason of this change.

You are right.
It worked for my needs because I am only building the drivers, and not
linking them. But i believe doing something like I did in zorro/Makefile
would fix this all. (For reference, https://lkml.org/lkml/2018/9/28/150 )

If you agree, I will send the next patchset with this change.

Thanks for your help!
