So if for example, there is no ".text" section, we have to
accomodate that. Except when explicitly adding symbol files at
some address, section_offsets contains nothing but zeros, so it
doesn't matter which slot in section_offsets the individual
sect_index_* members index into. So if they are all zero, it is
safe to just point all the currently uninitialized indices to the
