It's not the case of the MPC5200. It's enough with the -fPIC flag. It 
could be a problem with the gcc cross compiler/linker for the ppc4xx.

It should be the -fPIC flag. But I think that the main problem is the 
existence or not of a piece of code that copy the fixup section elements 
from flash to ram and adjust it as the powerpc code does it. I think we 
need the help of other architectures experts to resolve this doubt.

I think your right that having it wrapped in a conditional is the right way to start, but I would start with a patchset that fixes up all powerpc targets first and get it out for comments/testing before it gets merged to mainline.  Once powerpc is proven, then turn to look at the other architectures.

I agree.

I'm sorry but I've got not time to do this task by now. I'm not sure if 
this work must be done by only one persone or by the people who have the 
equipment to test it. Anway, if you are a volunteer for me is OK.
