scons: Enable the clang++ and clang tools.

If these tools aren't enabled and CXX isn't set, scons will look for
generically named compiler aliases like cc and c++. These will generally
work, but if scons knows that the compiler is specifically clang, it
will set the CXXCONFIG variable we can use to do compiler version
checking.

Because scons blindly forces a tool into use if you specify it, we need
to use the FindTool method which will check a list of tools and add the
first one that it actually finds.
