The test for __cxa_demangle(), which is used by Dune::className() to demangle type names, doesn't work on my clang 3.6. Apparently, clang requires the user to include <typeinfo> before <cxxabi.h>. While classname.hh already does this, the build system tests don't, causing the feature to get disabled on clang. Fixed by adding the include to the build system tests. (cherry picked from commit 70f52c0d) Signed-off-by:
