As I understand it, spidermonkey *does* use C++14 features (hence the need for
target GCC 4.9+). However, it also builds host tools which need only C++11
features, but the test is applied to host and target compiler indiscriminately.
The patch doesn't make a correct distinction between host and target, it just
generally lowers the minimum C++ version.
Now, given that they assume C++14 support is available, it's relatively likely
that they'll start using those features in future versions. At that point.
things will anyway break and we need this condition. So I'd say, byte the bullet
now and require hsot and target GCC >= 4.9.
