[gimp-help-2: 2/3] Add Makefile feature: use gimp po files as libraries

[Ulf-D. Ehlert <ulfehlert src gnome org>]

commit 9a485bfebaffaa3876057043e116b25ad3060a68

    Add Makefile feature: use gimp po files as libraries
    
    If make is called with GIMP_PO_ROOT set to the gimp repository
    directory (where the po directories are), the 'pot2po' routine
    will use po*/LANG.po files as libraries of message translations
    (see msgmerge(1), --compendium option).
