Update lwcc driver to actually do something useful sometimes
Make lwcc driver actually find the correct filenames for the preprocessor
and compiler.
Construct the preprocessor argument list correctly instead of assigning all
arguments to argv[0], including the trailing NULL argument.
Instruct lwasm to use the object file format.
Correct state setting for -S and -c options so they stop after the correct
phases of compilation.
