libupdate.sh: Add support for the new libupdate shell script. It

automatically updates a library from a file listing of constituent .o
files.  It only calls "ar" if it absolutely has to, in order to speed
things up for partial recompilations.  (ar is dreadfully slow if
you're using one based on the BFD library.)
