Is there anything I missed? This is unlikely to be buildroot-related... I would do a wireshark on the host to get more insight. You can also build a tcpdump for the target to verify if it even receives anything. Also try with a direct cable between host and target and static IP addresses, to rule out any influence of the switch. And one final thing I can think of is that there is some netfilter rule that disallows ping replies.
