I thought I had changed our patch to FindKDE4Internals.cmake in kdelibs4
to pass -fdelayed-template-parsing, but apparently I only committed
r9299. That's still weird, because r9299 removed "-fno-exceptions" from
the default C++ flags and smokekde itself does not explicitly change
those flags.

My guess is that our patch is outdated -- there was a clang-related
commit that got into 4.11.0 that made the GCC block be shared with
clang, so we're first getting the -fno-exception thing and later
repeating some flags in our own clang block in FindKDE4Internal.cmake.

If that's the case, I suppose there are at least a lot of unrecognized
compiler flags errors/warnings in your build logs.
