This is to enable relocation for code32. - RIP relative addressing is available in x86-64 only so we manually add relocation delta to the target symbols to fixup code32. - both code32 and code64 need to load GDT hence both need to fixup GDT pointer. This patch declares separate GDT pointer cpu_primary64_gdt_ptr for code64 to avoid double fixup. - manually fixup cpu_primary64_gdt_ptr in code64, but not rely on relocate() to do that. Otherwise it's very confusing that symbols from same file could be fixed up externally by relocate() or self-relocated. - to make it clear, define a new symbol ld_entry_end representing the end of the boot code that needs manually fixup, and use this symbol in relocate() to filter out all symbols belong to the entry sections.
