    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
    -----------------------
