The key word here is 'should'.  The rules should have @AMDEP_TRUE@
in front of them, looking at depend2.am below, they obviously won't.

This should be:
if %?LIBTOOL%
?GENERIC?%EXT%.lo:
?!GENERIC?%LTOBJ%: %SOURCE%
if  %AMDEP%
@AMDEP_TRUE@         source='%SOURCE%' object='%LTOBJ%' libtool=yes
@AMDEPBACKSLASH@
@AMDEP_TRUE@         depfile='$(DEPDIR)/%BASE%.Plo'
tmpdepfile='$(DEPDIR)/%BASE%.TPlo' @AMDEPBACKSLASH@
@AMDEP_TRUE@         $(%FPFX%DEPMODE) $(depcomp) @AMDEPBACKSLASH@
endif  %AMDEP%
         %LTCOMPILE% -c -o %LTOBJ% `test -f %SOURCE% ||
echo'$(srcdir)/'`%SOURCE%
endif %?LIBTOOL%

Shouldn't it?  I've taken my installed automake script, and added
@AMDEP_TRUE@ so it looks more like automake.in, and changed the
depend2.am file as noted above.  With these two changes dependency
tracking can be turned off, even when turned on when Makefile.in
is created.
