package/libclc: new package
This patch provides libclc, an open source implementation of the library requirements of the OpenCL C programming language, as specified by the OpenCL 1.1 Specification. It is intended to be used with Clover (Mesa3D's OpenCL implementation for AMD GPUs. It needs to be compiled with host-clang, as it generates LLVM IR bitcode files containing device builtin functions for each target. Currently, libclc supports AMDGCN, R600 and NVPTX targets. As OpenCL kernels can be built dynamically on the target using libclang and libLLVM, it is necessary to have clc headers installed on the target. Buildroot removes /usr/include in its target-finalize step, so clc headers are installed to /usr/share/clc.
