That was another reason for choosing libc++abi, it wasnt lacking 
anything in terms of features.

I can post my steps to build clang with g++ and libc++ and use it to 
compile other code. As I said earlier, compiling my code with 
clang/libc++ uses libstdc++ for ABI and unwind pieces (which I'm trying 
to remove). Even though your goal is different form mine, having a 
self-contained set of instructions to compile and use clang/libc++ will 
be helpful in general.
