Undefined symbol `_myip_ifp' referenced from text segment

[Pavel Korovin <pvk@tsinet.ru>]

hi all!
Trying to rebuild kernel for my home machine I've got the following error message:

8<---------
rm -f bsd
ld -z -Ttext F0100000 -e start -x -o bsd ${SYSTEM_OBJ} vers.o
if.o: Undefined symbol `_myip_ifp' referenced from text segment
*** Error code 1

Stop in /sys/arch/i386/compile/HIDEOUT.
--------->8

Can anybody help me with this problem? Kernel config attached.
Thanks.
