Abel Bernabeu 88cac04de3 package/llvm: Support for RISC-V on the LLVM package
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 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.
