Build AMDGPU target. Select this option if you are going

to install mesa3d with llvm and use Gallium Radeon driver.

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.
