Mingli Yu 3edad54298 MDEV-24131: unittest stacktrace-t fails to compile (OpenBSD)
This was because OpenBSD (and others) can be missing HAVE_BACKTRACE / HAVE_BACKTRACE_FD
which is the condition for my_safe_print_str to be defined.

Fixes:
/prj/tmp/work/cortexa57-poky-linux-musl/mariadb/10.5.8-r0/recipe-sysroot-native/usr/bin/aarch64-poky-linux-musl/../../libexec/aarch64-poky-linux-musl/gcc/aarch64-poky-linux-musl/10.2.0/ld.bfd: /usr/src/debug/mariadb/10.5.8-r0/mariadb-10.5.8/unittest/mysys/stacktrace-t.c:36: undefined reference to `my_safe_print_str'

Unit tests directory structure
------------------------------

This is the current structure of the unit tests.  More directories
will be added over time.

mytap                 Source for the MyTAP library
mysys                 Tests for mysys components
  bitmap-t.c          Unit test for MY_BITMAP
  base64-t.c          Unit test for base64 encoding functions
examples              Example unit tests.
  core-t.c            Example of raising a signal in the middle of the test
		      THIS TEST WILL STOP ALL FURTHER TESTING!
  simple-t.c          Example of a standard TAP unit test
  skip-t.c            Example where some test points are skipped
  skip_all-t.c        Example of a test where the entire test is skipped
  todo-t.c            Example where test contain test points that are TODO
  no_plan-t.c         Example of a test with no plan (avoid this)


Executing unit tests
--------------------

To make and execute all unit tests in the directory:

   make test

Observe that the tests in the examples/ directory are just various
examples of tests and are not expected to pass.


Adding unit tests
-----------------

Add a file with a name of the format "foo-t.c" to the appropriate
directory and add the following to the Makefile.am in that directory
(where ... denotes stuff already there):

  noinst_PROGRAMS = ... foo-t

Note, it's important to have "-t" at the end of the filename, otherwise the
test won't be executed by 'make test' !


Documentation
-------------

The generated documentation is temporarily placed at:

      http://www.kindahl.net/mytap/doc/

I will move it to a better place once I figure out where and how.
