As per commit 131b30c94fbc ("kselftest: exclude failed TARGETS from runlist") failed targets were excluded from the runlist. But value $$INSTALL_PATH is always NULL. It should be $INSTALL_PATH instead $$INSTALL_PATH.
So, fix Makefile to use $INSTALL_PATH.
I was a bit puzzled at first since I never saw the NULLified value while testing the original patch. Looking at it closely today, I realized that I used to test it like:
$ rm -rf $HOME/KSFT_TEST && make -C tools/testing/selftests/ INSTALL_PATH=$HOME/KSFT_TEST install
which in fact causes INSTALL_PATH to be exported down to the subshell in the recipe, so that even referring it as $$INSTALL_PATH from the recipe line make it work fine.
Instead, using the default Makefile provided value (unexported) by invoking like:
$ rm -rf $HOME/KSFT_TEST && make -C tools/testing/selftests/ install
exposes the error you mentioned, being INSTALL_PATH not accessible form the subshell and so NULL. Moreover it's anyway certainly better to refer with $(INSTALL_PATH) being it a strict Makefile var. So it's fine for me, thanks to have spotted this.

Thanks for Reviewing.
I have to send v2 patch with author mail id fix. I will keep your Reviewed-by.
