Actually the bootloader that I'm using (pbsdboot) DOES load all the
segments.  I've checked the code, and it's coded that way, plus I've checked
a sample app that has init data in the second loadable segment and it gets
inited properly.  I don't think the problem is in the bootloader - I now
think it is probably combination of elements from head.S, other symbols and
sections, and ld.script.little.
