Subject: [PATCH v2 1/4] perf build: Shellcheck support for OUTPUT directory
Migrate Makefile.tests to Build so that variables like rule_mkdir are
defined via Makefile.build (needed so the output directory can be
created). This requires SHELLCHECK being exported and the clean rule
tweaking to remove the files in find.
Change find "-perm -o=x" as it was failing on my Debian based Linux
kernel tree, switch to using "-executable".
Adding a filename prefix of "." to the shellcheck log files is a pain
and error prone in make, remove this prefix and just add the
shellcheck log files to .gitignore.
Fix the command echo so that running the test is displayed.
Fixes: 1638b11ef815 ("perf tools: Add perf binary dependent rule for shellcheck log in Makefile.perf")
Signed-off-by: Ian Rogers <irogers@...gle.com>
