scons: Increase the minimum clang version to 3.9.
This matches what's documented elsewhere. We *need* version 3.4 to
support c++14, but we support only as far back as 3.9. Also, the
argument to set c++14 as the standard is different in 3.4 and earlier
(-std=c++1y), so it makes life slightly easier to move past it to 3.9.
