  tests: more checks on portable fd redirection in TESTS_ENVIRONMENT
  
  * tests/tests-environment-fd-redirect.test: Extend by also using
  a perl script among the tests.  Run the test shell script with
  the `errexit' flag active.  Export `VERBOSE' to yes when running
  "make check", to give more debugging information in case of
  failures.  Look for a Korn Shell also in `/usr/bin', not on only
  in `/bin'.

  # Test for a behaviour of `TESTS_ENVIRONMENT' and `AM_TESTS_ENVIRONMENT'
  # w.r.t. file descriptor redirections which, although undocumented,
  # is nonetheless required by Gnulib's 'tests/init.sh' and by coreutils'
  # testsuite.
  # The checked behaviour is that we can portably do file descriptor
  # redirections by placing them at the end of a {AM_,}TESTS_ENVIRONMENT
  # definition without a following semicolon.  The need to support this
  # is detailedly motivated by coreutils bug#8846:
  #   <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=8846>
  # and the following CC:ed thread on bug-autoconf list:
  #   <http://lists.gnu.org/archive/html/bug-autoconf/2011-06/msg00002.html>
