* New snapshot release (3.4 release)
* Add a symlink of libLLVM-3.4.so.1 to usr/lib/llvm-3.4/lib/libLLVM-3.4.so
    to fix make the llvm-config-3.4 --libdir work (Closes: #708677)
  * Various packages rename to allow co installations:
    * libclang1 => libclang1-3.4
    * libclang1-dbg => libclang1-3.4-dbg
    * libclang-dev => libclang-3.4-dev
    * libclang-common-dev => libclang-common-3.4-dev
