[Bf-cycles] Cycles lib upgrade (LLVM / OIIO / OSL)

[Sergey Sharybin]

Oki, together with Jens we found rather simple solution:

- Build "vanilla" LLVM
- Build "vanilla" OpenCollada (well, not actually need to build it, just
use previous one, it was me who needed to rebuild it)
- Do NOT pass libUTF to blender's link libraries

This worked rather smooth on linux.
