Petko Bordjukov 644487e976 Drop condition to use libc++ on macOS
According to Apple, projects should be migrated to libc++[1]:

> Building with libstdc++ was deprecated with Xcode 8 and is not supported in
> Xcode 10 when targeting iOS. C++ projects must now migrate to libc++ and are
> recommended to set a deployment target of macOS 10.9 or later, or iOS 7 or
> later. Besides changing the C++ Standard Library build setting, developers
> should audit hard-coded linker flags and target dependencies to remove
> references to libstdc++ (including -lstdc++, -lstdc++.6.0.9,
> libstdc++.6.0.9.tbd, and libstdc++.6.0.9.dylib). Project dependencies such as
> static archives that were built against libstdc++ will also need to be rebuilt
> against libc++. (40885260)

WARNING: C++11 support is required for compiling mini_racer. Please make sure
you are using a compiler that supports at least C++11. Examples of such
compilers are GCC 4.7+ and Clang 3.2+.
If you are using Travis, consider either migrating your build to Ubuntu Trusty or
installing GCC 4.8. See mini_racer's README.md for more information.
