This should be applied on top of Luke's Blackfin patches.  It's a small 
enhancement for binfmt_flat; we didn't have enough space in the flat 
format for each relocation to store enough data, so this adds a method 
to keep data around and use it in a later reloc.  This is the minimum 
patch to get binfmt_flat working for normal apps on the Blackfin.
