    Merge branch 'maint'

    * maint:
      cosmetics: rename t/ax/test-runner => t/ax/runtest
      fixup: another "make recheck" failure with BSD make
      test runner: work correctly in VPATH setups
      compat: automake should define $(mkdir_p), for backward compatibility
      coverage: test that AM_PROG_MKDIR_P and $(mkdir_p) still works
      tests init: don't automatically re-execute tests with a POSIX shell
      yacc tests: fix spurious failure with parallel make
      tests: ignore minor 'recheck' regression for BSD make
      tests: don't clutter the top-level dir with temporary test directories
      tests: avoid spurious failures when @MKDIR_P@ points to "install-sh -d"
      lisp: better support of VPATH builds
      news: fixlets and updates

    + Extra non-trivial edits:

    * NEWS: State that $(mkdir_p) is still provided as an alias to
    $(MKDIR_P), for (partial) backward-compatibility.
