Some small amount of postprocessing is required after assembling
bootstrap.asm with a56. Add a script and makefile for this.

Downstream commercial distributors need to distribute the source code
as well as the binary.

keyspan_pda.S has an out-of-range decimal constant that looks
like it was really meant to be a binary constant. Comparing
with the binary, it appears that as31 used to treat this as 0,
so change the source to use 0 and add a comment on this.
