[PATCH v2 0/4] perf build: Linter parallelism and clean/install dependency fixes

[Ian Rogers]

This series includes a small Python test cleanup alongside build system
improvements for linter parallelism and clean/install target
dependencies:

1. Update tools/perf/tests/shell/lib/attr.py to use argparse instead of
   the deprecated optparse module, avoiding a pylint deprecated-module
   warning.

2. Building on Leo Yan's recent change to run pylint checks on
   standalone scripts and tests in parallel with linking perf, move the
   remaining shellcheck, mypy, and pylint rules (in tools/perf/Build,
   tools/perf/tests/Build, tools/perf/util/Build, and
   tools/perf/pmu-events/Build) into top-level phony targets in
   Makefile.perf so they no longer serialize archive creation, jevents
   generation, or final linking, nor wait on $(LANG_BINDINGS).

3. Clear GTK4 via 'override GTK4 :=' in Makefile.config when the gtk4
   feature check fails instead of setting the unused 'NO_GTK4 := 1'
   variable left over from commit 4751bddd3f98 ("perf tools: Make GTK2
   support opt-in").

4. Fix missing dependencies and target ordering for clean and install
   targets across Makefile, Makefile.perf, and
   Documentation/build-docdep.perl.

v2: In patch 4, exclude 'install-build-deps' from 'install_goals' in
    tools/perf/Makefile so it is not ordered after 'all', and explicitly
    order non-'clean' targets after 'install-build-deps' when present.

Ian Rogers (4):
  perf test: Update attr.py to use argparse
  perf build: Run shellcheck, mypy, and remaining pylint checks in
    parallel
  perf build: Clear GTK4 instead of setting unused NO_GTK4 when gtk4 is
    missing
  perf build: Fix clean and install target dependencies
