I'd try to use either both of: is_clang = false use_custom_libcxx = false or neither of them. Looks like the bundled Clang isn't happy with the sysroot's libcxx.
A possible alternative solution for making things work with non-default toolchains is treat_warnings_as_errors = false (and possibly fatal_linker_warnings = false as well).
