The raspberry pi uses the alternative API/ABI for OMX; this makes such builds incompatible with all the normal OpenMAX implementations. Since this can't easily be detected at configure time (one can build for raspberry pi's OMX just fine using the generic, pristine Khronos OpenMAX IL headers, no need for their own extensions), require a separate configure switch for it instead. The broadcom host library can't be unloaded once loaded and started; the deinit function that it provides is a no-op, and after started, it has got background threads running, so dlclosing it makes it crash.
