           Summary: graphics/opendx: make it build with clang 19 and
                    higher

In ports 0df8d006f641b ("Fix build on 14"), graphics/opendx was tied to
clang 15. Inspecting the configure script a bit, it turns out that
failures were due to clang 19 defaulting to -std=gnu++17 for C++
sources. (The configure script tries to define a macro 'byte' which is a
reserved identifier in the C++17 standard library).

Use USE_CXXSTD=gnu++11 to make it compile with base clang (19) on all
currently supported branches. Remove setting of CPPFLAGS, since that
will not work with C sources, if -std=gnu++11 is added to CXXFLAGS.
