Hi again! :)
 debugging a test pie code using qemu-ppc with your (and my little one) 
fixes I got this:
> start_brk   0x00000000
> end_code    0x400102e0
> start_code  0x40000000
> start_data  0x4001024c

> start_stack 0x40811438
> brk         0x400102e4
> entry       0x40828c24
that is start_brk is 0
As far as I understood brk is the .bss section, that is unitialized data 
area, am I right?
If not pls could you be so kind to explain me what it is, or pointing me 
to some document where it is explained.. among all material I am 
studying about linkers, relocations, I never found brk other than in qemu..
Once i am sure what it is I'll try to fix (if needed.. for me it is too 
strange it is zero) it..
Thank you again!
