This will not happen. At this stage, OUTPUT will not be empty.
I didn't explain the condition correctly in my change log. When OUTPUT
isn't set (which is the usual case when test is run using:
make -C tools/testing/selftests/futex run_tests
lib.mk sets it to OUTPUT := $(shell pwd)
So OUTPUT will be the current directory when run_tests are run.

The above change was made in conjunction with the
a8ba798bc8ec ("selftests: enable O and KBUILD_OUTPUT")
The above change didn't anticipate failures when tests are run outside
the selftests/Makefile umbrella via make -C tools/testing/selftests/testdir
