[Mesa-dev] [PATCH] scons: Fix build when rtti is disabled

[Alexander von Gluck IV]

* The rtti fix actually dug up a bug in the scons build scripts.
* Autotools took the LLVM cpp and cxx flags, while scons only took
  the cpp flags.
* This grabs the cxx flags and applies them where needed.
* I'm going to run over this and clean things up further, however
  this fixes the build where scons is used and rtti is disabled.
* The only linux platform I can find with LLVM no-rtti is Ubuntu.
* Resolved bug #70471
