- As of commit cb080a10b68(configure.ac: Don't require shared LLVM when
building OpenCL) opencl does not mandate using shared llvm.
- Add a warning message that building with static llvm may cause
compilation problems.
XXX: Tom please update the wiki [1]. Currently it lists the old configure
switch --with-llvm-shared-libs
