Description: Disable braindead KDE3/4 prefix detection
 The current detection of the KDE 3 and KDE 4 prefixes is done running
 kde-config and kde4-config, resp.
 This can be problematic, as these two could create files in ~/.kde,
 thus breaking when the home of the current user (eg in buildds) is read-only.
 Given the build system sets anyway "/usr" as prefix of KDE 3 and KDE 4
 if they were not detected, then just let it to.
