Subject: [PATCH] Fix libgstfsl linkage (add -lrt for shared memory functions).

Fixes runtime failure of gst-fsl-plugins, e.g.:
(gst-plugin-scanner:1700): GStreamer-WARNING **: Failed to load
	plugin '/usr/lib/gstreamer-0.10/libmfw_vpu.so':
	/usr/lib/libgstfsl-0.10.so.0: undefined symbol: shm_open)
