There are two reasons,
1. We need to do this after we load PT_LOAD segment, so that we have address
map which is essential to ReadMemory. PT_LOAD is usually after PT_NOTE afaik.
2. We need to do this after the core architecture is set, so
GetAddressByteSize() will return non zero value.

During the pass, it's parsing the elf header of the core file, during which we
don't have the gnu build id in there yet. We need to let the pass finish so
that we have the core file loaded into memory, and then we will need to read
from certain memory region which represent a loaded module and parse the elf
header there to get the gnu build id.
