+Subject: kbuild: Port silent mode detection to future gnu make.
+
+From: Dmitry Goncharov <dgoncharov@users.sf.net>
+
+commit 4bf73588165ba7d32131a043775557a54b6e1db5 upstream.
+
+Port silent mode detection to the future (post make-4.4) versions of gnu make.
+
+Makefile contains the following piece of make code to detect if option -s is
+specified on the command line.
+
+ifneq ($(findstring s,$(filter-out --%,$(MAKEFLAGS))),)
+
+This code is executed by make at parse time and assumes that MAKEFLAGS
+does not contain command line variable definitions.
+Currently if the user defines a=s on the command line, then at build only
+time MAKEFLAGS contains " -- a=s".
+However, starting with commit dc2d963989b96161472b2cd38cef5d1f4851ea34
+MAKEFLAGS contains command line definitions at both parse time and
+build time.
+
+This '-s' detection code then confuses a command line variable
+definition which contains letter 's' with option -s.
+
+$ # old make
+$ make net/wireless/ocb.o a=s
+  CALL    scripts/checksyscalls.sh
+  DESCEND objtool
+$ # this a new make which defines makeflags at parse time
+$ ~/src/gmake/make/l64/make net/wireless/ocb.o a=s
+$
+
+We can see here that the letter 's' from 'a=s' was confused with -s.
+
+This patch checks for presence of -s using a method recommended by the
+make manual here
+https://www.gnu.org/software/make/manual/make.html#Testing-Flags.
