Of course I realize you don't like the new GPL3 gcc versions, but in 4.8+ (and any future 4.7 releases), libstdc++ can be built independently. The latest LFS book does it gcc->libc->libstdc++

It also builds and works fine against the latest musl release, both cross-compiled and pseudo-natively (--build). I've been automating a static-musl-LFS bootstrap using pacman (https://github.com/smaeul/starch), and the only issue so far has been gcc autohell.

cmake is required for libcxxrt/libc++. LLVM itself works with autotools. cmake can also be bootstrapped with autotools.
