Build [email protected] with libc++ instead of libstdc++6

[jeroen]

My application builds with xcode on osx 10.11 and links against [email protected]. Everything builds however there are some runtime problems with c++ exceptions because [email protected] is built against libstdc++6 but my application uses libc++.

> otool -L /usr/local/opt/[email protected]/lib/libv8.dylib
/usr/local/opt/[email protected]/lib/libv8.dylib:
	/usr/local/opt/[email protected]/lib/libv8.dylib (compatibility version 0.0.0, current version 0.0.0)
	/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 104.1.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1238.50.2)
	/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 489.0.0)

> otool -L /usr/local/opt/v8/lib/libv8.dylib
/usr/local/opt/v8/lib/libv8.dylib:
	/usr/local/opt/v8/lib/libv8.dylib (compatibility version 0.0.0, current version 0.0.0)
	/usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 307.4.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1238.0.0)

Would there be a way to build [email protected] with libc++ instead? The v8 formula already uses libc++ but unfortunately it has a completely different API then [email protected] so upgrading is not an option.

Same problem as nodejs/node-gyp#469. Looks like old versions of gyp default to building a lib that is compatible with OSX < 10.7 which is when clang was still using libstdc++.

We need to pass -mmacosx-version-min=10.9 to the compiler/linker so that it will use libcxx.
