This patch adds a 'kcc' shell script that combines the sparse's i386

You can, for example, attempt to build sparse with itself and see it
crash and
burn:
make&& find . -name "*.o" | xargs rm
make CC=./kcc
CC test-lexing.o

For the record, the i386 backend is quite incomplete and awful.
Ideally, an sparse compiler would work from linearized output, not
from walking the tree as compile-i386 does.
Christopher, please drop this patch. I'm not planning to continue
hacking on compile-i386.c.
