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.
