*numerous* places where it was missing in the CMake build. The primary change here is that the suffix is now actually used for all of the lib directories in the LLVM project's CMake. The various subprojects still need similar treatment. This is the first of a series of commits to try to make LLVM's cmake effective in a multilib Linux installation. I don't think many people are seriously using this variable so I'm hoping the fallout will be minimal. A somewhat unfortunate consequence of the nature of these commits is that until I land all of them, they will in part make the brokenness of our multilib support more apparant. At the end, things should actually work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@224919 91177308-0d34-0410-b5e6-96231b3b80d8
