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.
