The initial support for the LLVM package did not include RISC-V, and needed to be added. Some special casing is needed for the LLVM_TARGETS_TO_BUILD variable, which expects a RISCV value regardless of whether riscv32 or riscv64 is chosen.

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.
