Allow to build LLVM with run-time type information as this feature is needed (for example) by mesa3d's Gallium Nouveau driver or the Clover OpenCL state tracker when llvm support is enabled in mesa3d. While we only care about RTTI support in the target, we also need to enable it in the host LLVM, so that llvm-config gives the proper result.

Build LLVM with run-time type information. LLVM can be built
|
|
without rtti, but turning it off changes the ABI of C++
|
|
programs.

This features is needed to build the Gallium Nouveau driver
|
|
or the Clover OpenCL state tracker when llvm support is

|
enabled.
