That's a very interesting point. As far as I can tell, XF_VERSION needs to
be incremented when either the global data data structure is modified, or
if functions are added to or removed from the export list. Commit
3469424cb6d939c7aedf1e0efdec44a797c0a18c seems to confirm this:

  Note that the location of the standalone application jump table pointer
  in the global data structure is affected by this change, breaking
  execution of standalone applications compiled for previous versions of
  U-Boot.

So I think your point about the #ifdef's in global data is very
interesting. There are a _lot_ of board level defines (LCD, PCI, POST etc)

Question for Wolfgang I think :)
