Building a custom kernel fails when bpf(4) is disabled as suggested in security(7) due to the error shown below. I also tried to define in make.conf WITHOUT_MODULES="lmc" or WITHOU_MODULES="if_lmc" assuming I could avoid building the culprit module/device, but it did not work as expected! I need to disable bpf(4). What is to do to avoid building this failing module?
