This feature is useful only for debugging stackleak gcc plugin.

The cflag that enables it is similar to -fplugin-arg-structleak_plugin-verbose,
which is used for debugging the structleak plugin.

This debugging feature clutters the kernel build output, I don't think that many
people will use it. So IMO creating a separate argument for make is not really
needed.

Thanks!
