Subject: [PATCH] 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.)
