#     kbuild: Port silent mode detection to future gnu make.
#     
#     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.
