Blackfin: support embedding the environment into loader files (LDRs)
For the most part, the Blackfin processor boots files in the LDR format rather than binary/ELF files. So we want to export the environment as a raw blob to the LDR utility so it can embed it at the right location. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
