# ScrapLinux's llvm-config --cxxflags never reports -stdlib=libc++, even though
# the libs it points at were built with it - rustc_llvm's build.rs greps
# cxxflags for that exact string to decide -lc++ vs -lstdc++, so it always
# falls through to -lstdc++ and leaves every std::__1::-namespaced (libc++)
# symbol in librustc_driver.so undefined at final link time. This is
# rustc_llvm's own documented override for exactly that mismatch.
