    Merge branch 'maint'

    * maint:
      tests: avoid few lingering $MAKE redirections
      tests: avoid '$MAKE' redirections, use 'run_make' instead
      tests: avoid use of redirected 'run_make' invocations
      lint: warn against redirected 'run_make' invocations
      comments: next GNU make release 4.0, not 3.83
      tests: fix a potential spurious failure due to global config.site
      HACKING: it's OK to do testsuite refactoring in a micro version
