Details:

Running the full test suite with '__run_test_suite__' uses chdir to change to
the directory that contains each test file.

The BIST test for help.cc requires that the current working directory is
writeable.

If Octave is installed first, let's say as root, and then the test suite is
run by a non-root user, the test will fail because the directory is not
writeable.

It should be possible to rewrite this test to write the function file to a
temporary directory, temporarily add that directory to the load path, and
remove it from the path in the unwind cleanup. Will take a look at that.


>> test ("/app/share/octave/5.0.90/etc/tests/libinterp/corefcn/help.cc-tst")
PASSES 1 out of 1 test
>> __run_test_suite__
({"/app/share/octave/5.0.90/etc/tests/libinterp/corefcn"}, {})

Integrated test scripts:

...
  libinterp/corefcn/help.cc-tst .................................. PASS    0/1
  
                                                                   FAIL    1
