When running 'make' in tools/testing/selftests/arm64/ without explicitly setting the OUTPUT variable, the build system will creates test directories (e.g., /bti) in the root filesystem due to OUTPUT defaulting to an empty string. This causes unintended pollution of the root directory. This patch adds proper handling for the OUTPUT variable: Sets OUTPUT to the current directory (.) if not specified Signed-off-by: tanze <tanze@kylinos.cn> Link: https://lore.kernel.org/r/20250515051839.3409658-1-tanze@kylinos.cn Signed-off-by: Will Deacon <will@kernel.org>
