Well, I've got something that seems to work for the R_PPC_LOCAL24PC 
relocation problem (already sent).  It might be too permissive, 
however.  Perhaps it should check that the referred-to symbol is 
_GLOBAL_OFFSET_TABLE_ before creating the GOT.  Although, if creating 
the GOT doesn't help resolve the symbol, the subsequent checks should 
fail, resulting in the same behaviour I was originally seeing (if the 
relocation doesn't reference the GOT symbol).

I'll have to do some more work for the other problem.  I'm highly 
motivated however, since our link times with GNU ld are excessive.

Thanks,
  Hamish.
