I set env variable MAKEFLAGS=w, and build bpftool it works fine too.
Maybe I miss something or debian changed top level Makefile?
Yes, but we don't change MAKEFLAGS or any of the logic around quietness
or verbosity.
I assume there are other factors involved, as I've also been unable to
construct a simple reproducer.
It would be good to know what is the exact problem, and then we can
decide whether this patch is the most appropriate fix or not.
Ben.
I am testing against latest bpf tree.
