I forgot .rela.got becomes part of the .rela.dyn section based on the
linker script. This accounts for the other 48 bytes, or 4 relocs that
appear in that section.

The problem is that during allocate_dynrelocs I only know it's
undefined, and it's not yet marked dynamic, and it doesn't have the
visibility set yet either. So I record it as a dynamic symbol, and
allocate it some space.

Later on it turns out to be hidden, and the space isn't needed, the
reloc isn't emitted.

I guess I somehow have to move this logic further back.
