It isn't with other instances in the Makefile. I'm not entirely sure all the ways that $(Q) is used (it looks like it just gets set to @), but if i run 'KBUILD_VERBOSE=1 make kselftest-merge' I do see the find command printed before running: find ./tools/testing/selftests -name config | \ xargs ./scripts/kconfig/merge_config.sh -m ./.config I noticed find used inconsistently (sometimes with @, sometimes with $(Q), sometimes with neither), so I picked the usage that seemed most correct to me.

Current implementation of kselftest-merge only finds config files that are one level deep using `$(srctree)/tools/testing/selftests/*/config`. Often, config files are added in nested directories, and do not get picked up by kselftest-merge. Use `find` to catch all config files under `$(srctree)/tools/testing/selftests` instead.
