kernel/module.c defines 
extern const char __start___kallsyms[] __attribute__ ((weak));
extern const char __stop___kallsyms[] __attribute__ ((weak));

The symbols are weak and do not need to be defined.  If gcc is not
honouring __attribute__ ((weak)) then you have a broken or obsolete
version of gcc.  You need at least gcc 2.91.66 for kernel 2.4.
