Thanks for steering me in the right direction. The problem was a mix
of two things:

1. I was having to incrementally increase the static sbrk size and
   still never getting enough because I didn't realize unexelf.c
   lacked code to set DUMPED to 1.

2. The failed bootstrap in lisp/ tree was leaving around stale/broken
   elc files that needed to be cleaned with "make bootstrap-clean".

I now have a working build with no ugly hackery. I'll share my patches
(mostly uninteresting) with the people doing dist packaging and see if
they can make something suitable for upstream.
