[U-Boot] ELF relocation issues wrt toolchain

[U-Boot] ELF relocation issues wrt toolchain

[Albert ARIBAUD]

All,

I think I've got the issue pinned down.

I noticed that in the non-working case, the _rel_dyn_start_ofs and 
_rel_dyn_end_ofs both had the same value. I first suspected a linker 
issue, when actually it was a linker *file* issue.

Somehow, between linker releases, the names of relocation input sections 
have changed, which moved them out of our .rel.dyn, actually causing the 
code not to relocate any more.

I am experimenting to find a solution that will please both 'old' and 
'new' linkers.

Amicalement,

We run all linker scripts through the C preprocessor. If there is a
version dependeny, we can handle this trough an #ifdef
