I just noticed this is in the BUGS section of make:
The determination of .OBJDIR is contorted to the point of
absurdity.

Why are you unable to do anything with the command-line? Any of these
will solve your problem.
Bourne:
MAKEOBJDIR=/no_obj_here make
Bourne or CSH:
env MAKEOBJDIR=/no_obj_here make
Here is a Makefile that does not use obj/. The special targets can be
placed into a file to be included into all your Makefiles. It only
suffers from a failed build where it will not rename obj to tmpobj.
-----------------------
.BEGIN:
mv tmpobj obj || mkdir obj
.INTERRUPT:
mv obj tmpobj
.END:
mv obj tmpobj
all:
touch testing
clean:
rm -f testing
