nm can't find strcat.o and friends in libkern

[talmage%cmf.nrl.navy.mil@localhost (David W. Talmage)]

I'm trying to make a custom kernel for NetBSD 1.3.  When I "make", nm
complains that it can't find the following .o files from libkern: _main.o,
imax.o, imin.o lmax.o, lmin.o, max.o, min.o ulmax.o, ulmin.o bcmp.o,
bzero.o, ffs.o, strcat.o, strcmp.o, strcpy.o, strlen.o, strncmp.o,
strncpy.o, htonl.o, htons.o, ntohl.o, ntohs.o, scanc.o, skpc.o, adddi3.o,
anddi3.o, ashldi3.o, ashrdi3.o, cmpdi2.o, divdi3.o, iordi3.o, lshldi3.o,
lshrdi3.o, moddi3.o, muldi3.o, negdi2.o, notdi2.o, qdivrem.o, subdi3.o,
ucmpdi2.o, udivdi3.o, umoddi3.o, xordi3.o.

ls ../../../../lib/libkern shows all of those .o files.

What gives?  Am I missing a simlink somewhere?
