…=Kobzol build `libcxx-version` only when it doesn't exist In rust-lang#126423, it seems like c++ parsing takes quite amount of time on bootstrap startups. This PR makes libcxx-version to be compiled only when it doesn't exist. A simple demonstration on the overhead of buiding `libcxx-version`: ```sh $ rm -rf build/host/libcxx-version $ x build Building bootstrap Finished `dev` profile [unoptimized] target(s) in 0.07s ----- LIBCXX VERSION CHECK TOOK: 509ms Building tool rustdoc (stage1 -> stage2, x86_64-unknown-linux-gnu) Finished `release` profile [optimized] target(s) in 0.25s Build completed successfully in 0:00:02 $ x build Building bootstrap Finished `dev` profile [unoptimized] target(s) in 0.07s ----- LIBCXX VERSION CHECK TOOK: 2ms Creating a sysroot for stage2 compiler (use `rustup toolchain link 'name' build/host/stage2`) Building tool rustdoc (stage1 -> stage2, x86_64-unknown-linux-gnu) Finished `release` profile [optimized] target(s) in 0.14s Build completed successfully in 0:00:01 ```
