lgtm

does this work?
there are load options (data right after text)
where you need the size of the last func
in order to lay out the first.

yes, i believe it works.
when the func gets laid out none of the data addresses
are filled in yet, but we know they're all 32-bit numbers
so it doesn't affect size.  once all the addresses are
known, after span() and dodata(), reloc() goes and fills them in.
