commit: https://git.buildroot.net/buildroot/commit/?id=46964be408402624d1bb7bd9e5896293627b141a
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2018.08.x

Suppose we use Makefile wrapper and build some project out of
buildroot tree (O=...). A command like "make
busybox-all-external-deps" will output the string "uname 022 && make
..." to stdout before the usefull information. It pollutes stdout. At
the same time if we use the same command in the buildroot source-tree
then we don't get the additional output. This patch makes wrapper
silent by default. People who prefer to see more verbose output can
use V=1.
