Romain Naour edad1d9f79 package/llvm: add llvm RTTI option
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 AMDGPU target. Select this option if you are going
to install mesa3d with llvm and use Gallium Radeon driver.
config BR2_PACKAGE_LLVM_RTTI
bool "enable rtti"
help
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.
