  tests: run_make: options to do command redirection
  
  Let's improve the API of the 'run_make()' helper shell function by
  adding three new options:
  
    -O   Save the standard output from make on disk, in a regular file
         named 'stdout'.
  
    -E   Save the standard error from make on disk, in a regular file
         named 'stderr'.
  
    -M   Save both the standard output and standard error from make on
         disk, in a regular file named 'output'. This option supersedes
         both the '-O' and '-E' options.
  
  This new API has two main advantages.
  
    1. Its use will allow us to get rid of more cumbersome idioms
       like, e.g.,
  
         $MAKE check >stdout && { cat stdout; exit 1; }
         cat stdout
  
       That can now be substituted with a simpler one:
  
         run_make -e FAIL -O check
  
    2. More importantly, using the new API we will prevent any extra output
       from the shell traces of the code in run_make to be redirected along
       with the make stderr (where that was redirected).  This problem was
       present in usages like, e.g.,
  
         run_make TESTS=foo.test check 2>stderr && exit 1
         grep 'expected error message' stderr
  
       Such usages are now to be rewritten as follows:
  
         run_make -e FAIL -E TESTS=foo.test check
         grep 'expected error message' stderr
  
       ensuring that 'stderr' won't end up containing unrelated stuff.
  
  Note that we do not convert in bulk the old idioms and the use of
  redirected 'run_make' invocations with this patch.  We only convert
  some occurrences, to ensure that the new implementation of 'run_make'
  is sound enough.  More sweeping conversions will likely be done in
  follow-up patches.
  
  * t/ax/am-test-lib.sh (run_make): Enhance and implement the extended API.
  * t/tap-xfail-tests.sh: Use the new 'run_make' API.
  * t/test-driver-cond.sh: Likewise.
  * t/tests-environment-fd-redirect.sh: Likewise.
  * t/uninstall-fail.sh: Likewise.
  * t/yacc-dist-nobuild.sh: Likewise.
