Well, three more ideas. Before running 'make *Image' but after running oldconfig in the above example check for the following:
1) check for NETFILTER_DEBUG in your .config file, it should look like this:
[adam@pepsi linux]$ grep NETFILTER_DEBUG .config # CONFIG_NETFILTER_DEBUG is not set
2) check the include/linux/autconf.h file
[adam@pepsi linux]$ grep NETFILTER_DEBUG include/linux/autoconf.h #undef CONFIG_NETFILTER_DEBUG
3) as final check you might want see what the actual o file contains. The first one below is compiled with CONFIG_NETFILTER_DEBUG enabled the second one is compiled with the said "feature" disabled.
[adam@pepsi linux ]$ nm net/core/netfilter.o | grep debug 00000338 t debug_print_hooks_ip 000005dc T nf_debug_ip_finish_output2 00000528 T nf_debug_ip_local_deliver 000005a0 T nf_debug_ip_loopback_xmit [adam@pepsi linux ]$ nm net/core/netfilter.o | grep debug [adam@pepsi linux ]$
