General source tree makefile cleanups: Made `making xxx in yyy...' display

General source tree makefile cleanups: Made `making xxx in yyy...' display
consistent in the source tree and replaced `/bin/rm' by `rm'.  Additonally
cleaned up the `make links' target: Remove unnecessary semicolons, subsequent
redundant removes, inline point.sh into mklink.sh to speed processing and no
longer clutter the display with confusing stuff. Instead only the actually
done links are displayed.
