 If we deprecate barebox pre-2012.10, then we can simplify this a lot:

config BR2_TARGET_BAREBOX_IMAGE_FILE
	string "Image file path"
	default "barebox-flash-image"
	help
	  Name of the built barebox image file in the barebox images directory


 Even if we don't want to deprecate barebox pre-2012.10, I'd prefer to keep this
simple config and do the handling of legacy barebox.bin in the .mk file. For
pre-2012.10, you'd have to explicitly set it to barebox.bin instead (which
should be mentioned in the help text then).

 We should find a good way to deal with the images/ part of the path, however.
This could e.g. be done in the .mk file, by checking both the top dir and the
images dir.

 Arnout
