    Merge branch 'master' into ng/master

    This merge fixes automake bug#11791 for Automake-NG as well.

    * master:
      tests: don't trust the exit status of "make -k" for non-GNU makes
      parallel-tests: reimplement fix for bug#11791
      tests setup: unset CDPATH
      tests setup: more namespace safeness
      tests setup: remove an unused variable
      tests setup: less hard-coding of the test subdirectory

    + Extra non-trivial edits:

    * lib/am/parallel-tests.am: Manually merge the new implementation of the
    fix for the bug#11791, as implemented by commit 'v1.12.1-95-gd5443e4' of
    mainline Automake.
    * Makefile.am (XFAIL_TESTS): Remove 't/parallel-tests-recheck-pr11791.sh'.
    Add 't/test-missing.sh', which is slightly broken by this patch.  A later
    patch will restore the lost behaviour.
