Then they are probably being referenced via the header-files.
For instance, if uclibc does not have a <sys/stat.h>, then
I would expect the compiler to "find" it under /usr/include

Use "nm" in the objects or obj_s, etc., directory to find the
objects that use those symbols.

You can see some details by making preprocessor-output files for
the corresponding sources, e.g., I see that toe.o uses the directory
function "readdir", so

        cd progs
        make toe.i

and I see on my machine that resolves to the "readdir64" symbol which is 
used in toe.o (looking at toe.i):

# 158 "/usr/include/dirent.h" 3 4
extern struct dirent *readdir (DIR *__dirp) __asm__ ("" "readdir64")
     __attribute__ ((__nonnull__ (1)));

(your configuration will be different of course)
