Please please please do not make 5 trees in 5 places with different
copies of ADLO and its legacy bios. This is not the way to go.

1. if it needs to be moved to payloads/ lets move it.
2. if we should switch to legacybios from Kevin O'Connor let's do this
too, or lets leave a choice.

It's not linked in at any point. It's loaded. Just like the linux kernel
loads ELF files. At least for v3 we can say for sure.
