If I use the MAKETARGET line as I entered it in my email, everything works as 
it should. However, if I edit the line to be:

 MAKETARGET = $(MAKE) --no-print-directory -C /.../some/other/path -f 
$(CURDIR)/Makefile \
                SRCDIR=$(CURDIR) $(MAKECMDGOALS)

Then I get

make[3]: *** No rule to make target `/.../some/other/path /Makefile'.  Stop.

It seems that $(CURDIR)/Makefile is pointing somewhere else.

I'm not sure I understand the question.

Given the above line make always loads $(CURDIR)/Makefile, because of the "-f 
$(CURDIR)/Makefile" command line option.  Because "-f" is given make doesn't 
look for the default Makefile in the working directory.
