Build with the unbundled libsass

If PKGCONFIG is set to YES in the proces environment, use pkg-config to locate system libsass to be linked. This way there is no need to checkout a src/libsass submodule at all and the library from the package management system can be used. Otherwise fallback to the bundled libsass. By default, use the bundled library. PR: 139 PR: 389 PR: 744
