You _could_ do something like this:

   make -f- << sed 's/MAKE_TARGET/\$@/' Makefile.descriptive

But for the sake of compatibility I wouldn't.

No need for ugly sed error-prone trickery.

Use on the Makefile:

    MAKE_TARGET := /some/path

And invoke

    $ make MAKE_TARGET=/other/path

His point was that all of $@, $%, $? have more descriptive names as well, you don't need to use these single character macros.

Also you probably meant ?= instead of := as the command you gave would still use /some/path instead of /other/path if you use :=.
