This patch adds a 'kcc' shell script that combines the sparse's i386 backend
with GCC and GNU assembler to make it easier for people to find bugs in sparse.
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
FIXME! no value for symbol preprocess_only. creating pseudo 1 (stack offset 4)

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.
