* harbour/bin/hb-func.sh
+ added support for displaying harbour bin, lib and include directories
for --hbbindir --hblibdir --hbincdir parameters.
Viktor please add such functionality also to hbmk2.
Only given directories should be displayed without any other
characters in the output.
Such feature allows to use -I`hbmk --hbincdir` in *nixes build
scripts what should greatly simplify 3-rd party projects make scripts.
