That seems a lot like what we've already done. I guess a GSOC student is working on the libcxxabi piece. The only advantage to using our runtime, libcxxrt, is performance and code size.‎

Currently the ebuilds for libunwind, libc++abi and libc++ all involve
some hackery to support standalone build. And the package clang is
just a placeholder, while it's actually built in llvm.

Maybe we can put them all into the llvm package, and control what
components to build via USE flags.
