Because DT properties are 4-byte aligned, and fitImage is a DT with long 
binary strings encoded in them. But that is not the case here, because 
the invocation does use mkimage -E .

Therefore I see two issues:
- Should the code which handles LEGACY fitImages with 4-byte alignment 
be fixed to relocate the blobs ? I think yes.
- Should mkimage -E align blobs to 8 bytes by default ? I think yes, and 
frankly, I thought it does so already, but apparently not.
