- Remove dynamic_size from struct elf_resolve.
- Replace all open coded dynamic handling with a function. Reduces size.
- Fold special MIPS dynamic code into the dynamic_info item.
- Add RELRO support.
- Support linking with "-z now".
- prepare for DT_RELACOUNT/DT_RELCOUNT optimization.
- Add -z now to ld.so linking, this is what ld.so does anyway so
let the linker know that.
