Subject: [PATCH] llvm: Build LLVM with run-time type information

> -D=LLVM_ENABLE_RTTI=ON: Used to build LLVM with run-time type
> information. This is required for building Mesa-19.0.4.

Required by Mesa 3D Nouveau driver.

    Dependency LLVM (modules: amdgpu, asmparser, bitreader, bitwriter, engine, ipo, mcdisassembler, mcjit, native) found: YES 7.0.1

    meson.build:1277:6: ERROR: Problem encountered: The Nouveau driver requires rtti. You either need to turn off nouveau or use an LLVM built with LLVM_ENABLE_RTTI.
