Yes, CMake build completes without errors for me, no need for i386 headers :)

$ cmake --version
cmake version 2.8.9

$ ls -1 lib/clang/3.2/lib/linux/
libclang_rt.asan-x86_64.a
libclang_rt.tsan-x86_64.a
libclang_rt.x86_64.a

$ ./bin/clang -v
clang version 3.2 (trunk 165441)
Target: x86_64-unknown-linux-gnu
Thread model: posix
