Added make *-diff rules, quick commands to compare sizes

Browse Source 
This required a patch to the --diff flag for the scripts to ignore
a missing file. This enables the useful one liner for making comparisons
with potentially missing previous versions:

    ./scripts/code.py lfs.o -d lfs.o.code.csv -o lfs.o.code.csv

    function (0 added, 0 removed)            old     new    diff
    TOTAL                                  25476   25476      +0

One downside, these previous files are easy to delete as a part of make
clean, which limits their usefulness for comparing configuration
changes...
