[PATCH] kbuild: introduce KECHO convenience echo

[PATCH] kbuild: introduce KECHO convenience echo

[Mike Frysinger]

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.

[PATCH] kbuild: use KECHO convenience echo

[Mike Frysinger]

Convert a few echos in the build system to new $(KECHO) so we get correct
output according to build verbosity.

Nice idea.
I will add it as soon as I start working on kbuild-next
Same for your other two patches.

A lot of the kbuild stuff today is using lowercase to
avoid all the typical SCREAMING in Makefiles so I
may end up using $(kecho).

yeah i wasnt sure whether to use $(KECHO) or $(kecho) or just $(echo).

Applied both with a few mods. I will post full kbuild serie
tomorrow.
