Hi Jeff, please drop this patch, I found after bisecting and finding a
commit in January of 2019 that causes my issue, that if I just change
the command sequence I do, everything works fine.

FAIL: make O=../foo.obj M=drivers/net/ethernet/intel/i40e

PASS: make O=../foo.obj M=`pwd`/drivers/net/ethernet/intel/i40e

So the change in behavior is somewhat introduced recently (a year ago)
but me just having to learn a new trick is better than trying to fix
this in the kernel.
