I do not quite follow you here.

For a while I have considered implementing something that told why a
given file was compiled - like:

CC net/ipv4/ip_gre.o due to net/dsfield.h, net/xfrm.h
CC net/ipv4/raw.c due to include/config/ip/mroute.h

The latter is a config option that I do not see a possibility to change
back to a config option syntax (at least not without doing some effort).

My thinking was that 'make V=2' would give above printout.

But what you request is something that keep the dense printout without
building the kernel - right?

Any suggestion for an intuitive syntax to enable that?
'make -n V=2' will not do it.
