From 5410ecc0def8955ab99810c5626cc7e156991896 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Thu, 6 Nov 2008 03:31:34 -0500 Subject: kbuild: introduce $(kecho) convenience echo There is a bunch of places in the build system where we do 'echo' to show some nice status lines. This means we still get output when running in silent mode. So declare a new KECHO variable that only does 'echo' when we are in a suitable verbose build mode.
