[PATCH v2 0/5] t/unit-tests: improve clar platform compatibility

Hi,

this is the second version of my patch series that addresses some platform compatibility issues with clar. Changes compared to v1:

  - I've merged the CMake fixes at [1] into this patch series to avoid
    conflicts. @Taylor, please drop that other series, which is
    "ps/cmake-clar".

  - I've fixed up the "generate-clar-decls.h" script.

  - I've updated the clar such that it includes upstreamed changes for
    improved uClibc support when we lack support for `wchar_t`.

Thanks!

Patrick

         discussed in Git when initial support for clar was merged:

           - We now use the combination of mktemp(3) and mkdir(3) on SunOS, same
             as we do on NonStop.
     
    +      - We now support uClibc without support for <wchar.h>.

         The most important bits here are the improved platform compatibility
    -    with Windows, OpenSUSE and SunOS.
