issue 18515: Fix it so that neither g++ nor CC is required.

It was previously fixed so that cc is used if CC isn't set when
compiling dmd, but the test suite still had g++ hardcoded, so if the
system was set up with clang and not gcc, the dmd test suite barfed
midway through. This fixes it so that it uses c++ if CC isn't set
instead of using g++.
