Is there a way to print the exact command that's being invoked from
Make? For example, some of the macro's in scripts/Kbuild.include are
tricky to unwind. Is there a way to dump each sub command being run?

Yamada-san can answer that much better than I can.
I just begin with "make V=1" for verbose command logging.
and it will be verbose.

There always is strace... Or maybe make -dj and friends.

Hmm...I'm debugging a 4.9 LTS based kernel. `make V=1` and `make -dj`
were things I tried, but don't seem to be printing the commands being
executed (only "Reading makefile ...") until the first warning is hit.
I wonder if someone is setting the quiet variable somehow, or if I'm
missing a patch...
Thanks for the ideas.

Yeah, that sounds like -s (silent) is set.
