buildkernel broken on if_ixl when EVDEV is enabled

[Pete Wright]

howdy - just ran into an issue with building a kernel that has EVDEV 
enabled causing this error:

--- kernel.full ---
linking kernel.full
ld: error: undefined symbol: ixl_iw_pf_init
 >>> referenced by if_ixl.c:900

*** [kernel.full] Error code 1


building a standard GENERIC kernel works without issue.  my "EVDEV" kern 
conf has the following two lines added:

options         EVDEV_SUPPORT           # D10265 from phabricator
device          evdev

Not sure if anyone else has seen this?
