Sounds like pkg-config is not providing you with the required deps.
Since you're doing a static build with static external libraries, try
adding "--pkg-config-flags=--static" to your configure line.

Adding --static to --pkg-config-flags might let you remove some of these
custom ldflags. But probably not all.
