[PATCH] Add an extra flag to libcxxabi buildit to link compiler runtime libraries

[Keno Fischer]

I tried that first, though I couldn't get it to work. I want to
bootstrap a make&configure based llvm build with libcxx and libcxxabi.
I'm using Cmake for libcxx, but libcxxabi seems to be coupled to
llvm-config.
