Modify the documentation that discusses how to override INSTALL_PATH

    Modify the documentation that discusses how to override INSTALL_PATH
    to describe setting of $DESTDIR instead.

    Don't add a slash before INSTALL_PATH if DESTDIR is empty since this
    breaks installation on Windows.  (This change has already been made
    in Mmake.common.in)

    Set more FINAL_INSTALL_ variables to support the new code in
    Mmakefile and bindist.Makefile.in.

Mmake.common.in:
    Improve the prose in a comment.

Mmakefile:
    Update installation message.

    Tell the user that their install is in $(DESTDIR) if applicable.

    Use FINAL_INSTALL variables rather than INSTALL variables.
