It was a method I found online without really understanding what X-Forwarded-For header does. Traffic does not pass through a reverse proxy before hitting HAProxy. It should be a direct hit from the client. Is there a header I can compare to our whitelist to reliably get all incoming

This means that you have incompatible (from the point of view of ld) versions of libcrypt.so and libc.so that would have otherwise been first preference to resolve the dependencies, but since the compilation succeeded those apparently were found somewhere else. If haproxy starts up and is able to
