Eu am facut ceva la stilul urmator, mai demult. In mod particular,
comanda de mai sus care extrage sectiunile relevante din ELF probabil
e mai buna decat la mine.
In loc de "ld -Ttext 0" poti sa pui ce adresa de start vrei tu.
O alta chestie cool de care probabil o sa ai nevoie e ca in fisierul
obiect pe care ti-l scoate ld-ul ai definite simbolurile:
__bss_start
_edata
_end
_etext
