It is part of it. The relocation type also says where to write (bits
10-21 for example), which is why I went with expr: it mostly just
shows which expression the relocation computes.

I will upload a new WIP patch in a second.

The final version I want to commit has far fewer enums by representing
the target by just addend and output section. With that representation
we don't need, for example, R_PC and and R_GOT_PC.

Cheers,
Rafael
