commit bcb27939465ea192186d20aa8801db722dcb1bf4
Author: Raymond Toy <toy.raymond at gmail.com>

Remove darwin-lispadjuster.c and ppc-darwin-dlshim.c
Use of ppc-darwin-dlshim.c was removed, but I forgot to remove the
file.
Use of darwin-lispadjuster.c has been commented out for a while, so
I'm getting rid of it. It seems at one point it was needed to resize
the CMUCLRO section in the lisp executable, but there is CMUCLRO
section anymore.
darwin-lispadjuster.c:
* Deleted
ppc-darwin-dlshim.c:
Config.ppc_darwin:
* Remove Make rule for adjustlisp and friends.
* Remove old commented out version of OS_SRC; we don't use
ppc-darwin-dlshim.c anymore.
