Multiboot direct loading broken.
Description of problem:
This is my kernel and it's multiboot loader. It passed the check of `grub-file`, but QEMU could not load it.
```
qemu-system-i386: Error loading uncompressed kernel without PVH ELF Note
```

When I add `-machine type=pc-i440fx-3.1`, QEMU shows `qemu: linux kernel too old to load a ram disk` or `qemu: invalid kernel header`.

The multiboot file is linked with `ld.lld -s -o`.
