Binfmt_flat: Add minimum support for the Blackfin relocations
Add minimum support for the Blackfin relocations, since we don't have
enough space in each reloc. The idea is to store a value with one
relocation so that subsequent ones can access it.
Actually, this patch is required for Blackfin. Currently if BINFMT_FLAT is
enabled, git-tree kernel will fail to compile.
