#     kbuild: revive "Entering directory" for Make >= 4.4.1
#     
#     With commit 9da0763bdd82 ("kbuild: Use relative path when building in
#     a subdir of the source tree"), compiler messages in out-of-tree builds
#     include relative paths, which are relative to the build directory, not
#     the directory where make was started.
#     
#     To help IDEs/editors find the source files, Kbuild lets GNU Make print
#     "Entering directory ..." when it changes the working directory. It has
#     been working fine for a long time, but David reported it is broken with
#     the latest GNU Make.
#     
#     The behavior was changed by GNU Make commit 8f9e7722ff0f ("[SV 63537]
#     Fix setting -w in makefiles"). Previously, setting --no-print-directory
#     to MAKEFLAGS only affected child makes, but it is now interpreted in
#     the current make as soon as it is set.
#     
#     [test code]
#     
#       $ cat /tmp/Makefile
#       ifneq ($(SUBMAKE),1)
#       MAKEFLAGS += --no-print-directory
#       all: ; $(MAKE) SUBMAKE=1
#       else
#       all: ; :
#       endif
#     
#     [before 8f9e7722ff0f]
#     
#       $ make -C /tmp
#       make: Entering directory '/tmp'
#       make SUBMAKE=1
#       :
#       make: Leaving directory '/tmp'
#     
#     [after 8f9e7722ff0f]
#     
#       $ make -C /tmp
#       make SUBMAKE=1
#       :
#     
#     Previously, the effect of --no-print-directory was delayed until Kbuild
#     started the directory descending, but it is no longer true with GNU Make
#     4.4.1.
#     
#     This commit adds one more recursion to cater to GNU Make >= 4.4.1.
#     
#     When Kbuild needs to change the working directory, __submake will be
#     executed twice.
#     
#       __submake without --no-print-directory  --> show "Entering directory ..."
#       __submake with    --no-print-directory  --> parse the rest of Makefile
#     
#     We end up with one more recursion than needed for GNU Make < 4.4.1, but
#     I do not want to complicate the version check.
