 You seem to be curing the symptoms here, it looks like a bug in binutils 
to me.  The _gp_disp symbol has no fixed value (it's "distance from PC to 
GP" used for relocs in text; it has special rules even for that, to 
determine the actual value of the PC to be used against) and as such it 
shouldn't get past the static link.  I can see it's now exported as a 
dynamic symbol even.

 Richard, do you happen to know what is going on here?
