Fix Qtopia build

Fix Qtopia build issues

This patch fixes two Qtopia build issues, encountered while trying to use system implementation of zlib, freetype, jpeg and libpng :

* The build process doesn't look in $(STAGING_DIR)/usr/include for includes and $(STAGING_DIR)/usr/lib. Same problem as the patch currently floating around adding LDFLAGS to TARGET_CONFIGURE_OPTS, but as Qtopia doesn't use TARGET_CONFIGURE_OPTS, we need a specific fix here. So we use the -I and -L options of Qtopia's configure script.

* The build process doesn't use pkg-config to get the header path for Freetype headers (located in $(STAGING_DIR)/usr/include/freetype2 and not directly in $(STAGING_DIR)/usr/include/). There was already a fix for this, consisting in adding $(FREETYPE_DIR)/include to the -I path of Qtopia's configure. This patch modifies this fix to use $(STAGING_DIR)/usr/include/freetype2 instead, which looks more coherent with how all the packages are built (using $(STAGING_DIR) as the reference to get headers and libraries).
