Subject: support/scripts/mkmakefile: make wrapper silent by default
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c77cd170826e6430315f56a5c4d44ee97cc83050;p=buildroot.git

support/scripts/mkmakefile: make wrapper silent by default

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.
