On Unix, use pkg-config to determine the required compiler flags and libs for OpenAL.
Doomsday plugins must export their public symbols as extern C. Changed the driver interface exported from dsOpenAL to extern C, and made the plugin's state variables static so they won't interfere with the engine's symbols (-rdynamic, we need to get rid of you).
