[PATCH] kbuild: Fix silent builds with make-4

From: Emil Medve
Date: Thu Dec 05 2013 - 17:21:40 EST


make-4 changed the way/order it presents the command line options
into MAKEFLAGS

In make-3.8x, '-s' would always be first into a group of options
with the '-'/hyphen removed

$ make -p -s 2>/dev/null | grep ^MAKEFLAGS
MAKEFLAGS = sp

In make-4, '-s' seems to always be last into a group of options
with the '-'/hyphen removed

$ make -s -p 2>/dev/null | grep ^MAKEFLAGS
MAKEFLAGS = ps
