Caused by

config IR_TTUSBIR

which selects USB but does not have the necessary dependency on USB_ARCH_HAS_HCD.

Introduced by commit 0938069fa08970f1c898970c1331a029efe9a1ce "[media] rc: Add
support for the TechnoTrend USB IR Receiver".

Fixing this exposes

ERROR: "usb_kill_urb" [drivers/media/usb/gspca/gspca_main.ko] undefined!
ERROR: "usb_set_interface" [drivers/media/usb/gspca/gspca_main.ko] undefined!

ERROR: "usb_alloc_urb" [drivers/media/usb/gspca/gspca_main.ko] undefined!

which I think is due to CONFIG_USB_GSPCA=m, but I have no idea how that can be
enabled w/o USB support.
