Hello Fran?ois,

Overall looks good, was about to apply, but I have a couple of
comments/questions, see below.

We don't typically use the <pkg>_CONFIG_SCRIPTS variable from another
package, because it may contains multiple entries, so please stick to:

	GDLIBCONFIG=$(STAGING_DIR)/usr/bin/gdlib-config

What is this $(GD_VERSION)r3 thing ? Why r3 ? If it's really needed
as-is, it deserves a small comment.

Please add an explicit -m option to define the permissions.

Thanks!
