openscenegraph fails to cross build from source, because it uses
CHECK_CXX_SOURCE_RUNS. The invocation around atomics is difficult to
avoid, but the one for poppler-glib is quite easy to avoid. Hence I'm
sending a patch for the latter to incrementally move things forward. We
may use CHECK_SYMBOL_EXISTS there instead.
