Without this patch, the .la file only added -lncurses without
specifying the nix store path, forcing the propagation
of ncurses as build input.
Also enable parallel building and add myself to the maintainers.
This change has been successfully tested on gnome 3.12 (thanks
@lethalman!). Now bring it to gnome 3.10, which currently is the default
gnome3 version in NixOS.
I've build and run tested it (success: smb:// protocol now work in
Nautilus).
