Here's what I use for a silent build:

    brmake() {
        make "${@}" \
        |sed -r -e '/^.{4}>>>[[:space:]]+(.*).{5}$/!d; s//\1/;'
    }

Then calling 'brmake' instead of 'make', will get you only the >>> lines.

Of course, does not work if you invoke a CLI configurator, either
directly, or as a consequence of a missing .config. I basically
always call it with no argument, otherwise, I use plain 'make'.
