Attachment: Bug 1604616 - check for a new enough libstdc++; r=#build

After a C++ language version bump, It's possible to wind up in
situations where we are using a new enough compiler version, but the
libstdc++ version in use is not new enough to support new language
features: self-compiled clang with system libraries, clang from mach bootstrap prior to C++ language version bump (and thus including a new
libstdc++ with the boostrapped clang), etc.

Previously, such a situation would mean that things would work fine, and
then start breaking as soon as new library features started to be used.
Let's try to catch the problem earlier, when the update happens, by
verifying that the libstdc++ version is at least as new as the GCC
version we're requiring.
