Tumbleweed CI image and KDECompilerSettings

[João Gouveia]

Hi everyone,

It seems that the CI image for OpenSUSE's Tumbleweed does not use a 
version of Clang that supports the -fhardened compiler flag (see this 
job log 
<https://invent.kde.org/joaotgouveia/mankalaengine/-/jobs/2411881>, line 
484). This flag is being set by ECM's KDECompilerSettings (source 
<https://github.com/KDE/extra-cmake-modules/blob/master/kde-modules/KDECompilerSettings.cmake#L614C1-L614C60>). 
Am I misconfiguring something, or is this a genuine issue? If this is 
not the appropriate place to discuss this, please let me know.

Best regards,

João
