Will do, thanks. Maybe Documentation/SubmitChecklist and
Documentation/development-process/4.Coding wants to be updated.

It did indeed work, but only because I passed the setting on the make
command line and not via the environment. I think one needs an override
directive to actually override the settings from the command line:
$ cat Makefile
VAR1 := a1
VAR2 := a2
override VAR3 := a3
override VAR4 := a4
all:
@echo $(VAR1) $(VAR2) $(VAR3) $(VAR4)
$ VAR1=b1 VAR3=b3 make VAR2=b2 VAR4=b4 all
a1 b2 a3 a4
