Hi Thomas, Greg, Steve & Reco,

sorry for the late reply, but thank you all for the hints! :)

all done in tmux window with configure for GnuPG 2.2.11:

user:/opt/git/gnupg-2.2.11$ ./configure
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... /bin/mkdir -p
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking whether make supports nested variables..

~$ ps -ef | fgrep make
user    27190 26927  0 21:37 pts/9    00:00:00 make -f -

from GnuPG 2.2.11 configure:

{ $as_echo "$as_me:${as_lineno-$LINENO}: checking whether $am_make
supports nested variables" >&5
$as_echo_n "checking whether $am_make supports nested variables... " >&6; }
if ${am_cv_make_support_nested_variables+:} false; then :
  $as_echo_n "(cached) " >&6
else
  if $as_echo 'TRUE=$(BAR$(V))
BAR0=false
BAR1=true
V=1
am__doit:
	@$(TRUE)
.PHONY: am__doit' | $am_make -f - >/dev/null 2>&1; then

user:/opt/git/gnupg-2.2.11$ bash -x ./configure:

+ printf '%s\n' 'configure:3380: checking whether make supports nested
variables'
+ printf %s 'checking whether make supports nested variables... '
checking whether make supports nested variables... + false
+ make -f -
+ printf '%s\n' 'TRUE=$(BAR$(V))
BAR0=false
BAR1=true
V=1
am__doit:
        @$(TRUE)
.PHONY: am__doit'

(end)

user:/opt/git/gnupg-2.2.11$ export \
am_cv_make_support_nested_variables=yes

user:/opt/git/gnupg-2.2.11$ ./configure
-> worked:
checking whether make supports nested variables... (cached) yes
