Subject: [PATCH] android: enable the radeonsi driver

Based on the nice work of Paulo Sergio Travaglia <pstglia@gmail.com>.

The main modifications are:

- Include paths for LLVM header files and shared/static libraries
- Set C++ flag "c++11" to avoid compiling errors on LLVM header files
- Set defines for LLVM
- Add GALLIVM source files
- Changes path of libelf library for lollipop
