Review request for Build System, Andreas Pakulat, Alexander Neundorf, and Stephen Kelly.


Changes
-------

extended description + testing done


Description (updated)
-------

When building KDE applications with clang, multiple issues arise:

- debugfull is not supported at all, it's as if one gives an 'invalid' build type to cmake (i.e. neither -O nor -g is present)
- most of the "pedantic" flags are not set properly, such as those that ensure proper visibility macros etc. pp.
- none of the above is communicated to the developer, the might compile for him but not work as expected or he will introduce issues for others (like the windows guys)

This patch lets clang use the same codepaths as gcc which works due to its CLI compatibility interface.
