Ditto! My requirement was slightly different. I have a structure like this

repository/
  tool1/
    Makefile@ -> ../tool.makefile
  tool2/
    Makefile@ -> ../tool.makefile
  tool.makefile

In other words, my tool makefiles are symlinks to the main makefile. In this case the above code always resolves to the repository path.

But changing it to:

ROOT_DIR:=$(realpath $(shell dirname $(firstword $(MAKEFILE_LIST))))

test:
  @echo $(ROOT_DIR)

resolved this resolution issue for me
