don't know how to make /usr/src/sys/arch/x86/x86/iclockmod.c. Stop

Hi,

since last update of /usr/src (Friday evening), I can't build my
customized kernel
with following error:

ERROR: Failed to make depend in "/usr/obj/usr/src/sys/arch/amd64/compile/BERT"

Compiling GENERIC seems not to have this problem (either anything isn't included
or any additional option is there which is missing in my kernel configuration).
I've tried to compare my customized kernel with sys/arch/amd64/conf/GENERIC, but
I didn't found a missing entry pointing to iclockmod.

Any suggestions?

Thanks in advance,
Jens
