[gnome-music/wip/merge: 211/343] Load libgd from source dir if we are running there

[Ignacio Casal Quinteiro <icq src gnome org>]

commit 577bde318f6ea9d332f738846055db3af69a3eed
Author: Arnel A. Borja <arnelborja src gnome org>
Date:   Wed Jul 17 19:22:15 2013 +0800

    Load libgd from source dir if we are running there
    
    Makes sure that when we run inside the source dir, the source files and
    current build of libgd will be used instead of the installed ones.
