Since commit f2f02ebd8f38 ("kbuild: improve cc-option to clean up all temporary files") when building powerpc/ from selftests directory, the OUTPUT directory points to powerpc/pmu/ebb/ and gets removed when checking for -no-pie option in try-run routine, subsequently build fails with the following: $ make -C powerpc ... TARGET=ebb; BUILD_TARGET=$OUTPUT/$TARGET; mkdir -p $BUILD_TARGET; make OUTPUT=$BUILD_TARGET -k -C $TARGET all make[2]: Entering directory '/home/linux-master/tools/testing/selftests/powerpc/pmu/ebb' make[2]: *** No rule to make target 'Makefile'. make[2]: Failed to remake makefile 'Makefile'. make[2]: *** No rule to make target 'ebb.c', needed by '/home/linux-master/tools/testing/selftests/powerpc/pmu/ebb/reg_access_test'. make[2]: *** No rule to make target 'ebb_handler.S', needed by '/home/linux-master/tools/testing/selftests/powerpc/pmu/ebb/reg_access_test'. make[2]: *** No rule to make target 'trace.c', needed by '/home/linux-master/tools/testing/selftests/powerpc/pmu/ebb/reg_access_test'. make[2]: *** No rule to make target 'busy_loop.S', needed by '/home/linux-master/tools/testing/selftests/powerpc/pmu/ebb/reg_access_test'. make[2]: Target 'all' not remade because of errors. Fix this by adding a suffix to the OUTPUT directory so that the failure is avoided.
