After some discussion on #llvm it turned out to be a known issue in LLVMLinux!

Unfortunately, an existing patch [1] got archived which is still
required to build x86_64 correctly.
I refreshed this patch against Linux v4.2 (see file attachments).
( According to llvm guys that patch should go upstream and affects
also building with GCC. )
( That's up to the experts. )
