+ hbmk2 executable if renamed, copied or symlinked to the
name 'harbour', it will make it behave as classic harbour
executable, or IOW it will switch to hbmk2 -hbraw mode in such
scenario. This makes it possible to continue using 'harbour'
as a command even in distros which don't ship with classic
harbour executable.
