[PATCH] lib/scatterlist.o needed by a module only - link it in unconditionally

[Guennadi Liakhovetski <g.liakhovetski@pengutronix.de>]

lib/scatterlist.c is needed by drivers/media/video/videobuf-dma-sg.c, and 
we would like to be able to use the latter without PCI too, for example, 
on PXA270 ARM CPU. It is then possible to create a configuration with 
CONFIG_BLOCK=n, where only module code will need scatterlist.c. Therefore 
it must be in obj-y.
