Details:

gmake seems to be printing what the directory was prior to the launching of a
sub make that disables jobserver mode with -j1. The submake is started in the
correct directory, but the wrong one is printed in the "Entering directory"
message. 

This inconsistency in messages was not present in gmake 3.82 (Debian 7, 9,
MacOS 10.10, Windows 7). I have reproduced the behavior with gmake 4.1 (on
Debian 9) and with gmake 4.2.1 (on Debian 7, 9, 10, MacOS 10.10, Windows 7) 

Simple makefiles attached to reproduce the behavior.

% pwd
/tmp/a

------------ All Correct ---------
% gmake -w 
gmake: Entering directory '/tmp/a'
gmake -C /tmp/a/b/c
gmake[1]: Entering directory '/tmp/a/b/c'
echo /tmp/a/b/c
/tmp/a/b/c
gmake[1]: Leaving directory '/tmp/a/b/c'
gmake -C /tmp/a/b/d -j1
gmake[1]: Entering directory '/tmp/a/b/d'
echo /tmp/a/b/d
/tmp/a/b/d
gmake[1]: Leaving directory '/tmp/a/b/d'
gmake: Leaving directory '/tmp/a'

------------ Second submake incorrectly reports "Entering directory '/tmp/a'"
instead of Entering directory '/tmp/a/b/d' ---------
% gmake -w -j2
gmake: Entering directory '/tmp/a'
gmake -C /tmp/a/b/c
gmake[1]: Entering directory '/tmp/a/b/c'
echo /tmp/a/b/c
/tmp/a/b/c
gmake[1]: Leaving directory '/tmp/a/b/c'
gmake -C /tmp/a/b/d -j1
gmake[1]: Entering directory '/tmp/a'
gmake[1]: warning: -jN forced in submake: disabling jobserver mode.
echo /tmp/a/b/d
/tmp/a/b/d
gmake[1]: Leaving directory '/tmp/a/b/d'
gmake: Leaving directory '/tmp/a'
