Implement relocation for M68K. Perform all the updates in start.S relocate_code in assemby, since it is a simple matter of traversing the dynsym table and adding relocation offset - MONITOR_BASE to all the items in that table. The necessity to deal with MONITOR_BASE is a specific of M68K, where the ELF entry point is at offset 0x400, which is the MONITOR_BASE, while TEXT_BASE is at offset 0 .
This also removes the one last user of NEEDS_MANUAL_RELOC, so that could be finally cleaned up .
