It's related to the upstream kernel commit adf82accc5f5 ("netfilter:

Signed-off-by: Rafał Miłecki <rafal@milecki.pl>
In mainline kernel commit 02c7b25e5f5 ("netfilter: nf_tables: build-in
filter chain type") all chain filters were merged into one file and into
one kernel module to save some memory. The code protected by these
configuration options CONFIG_NF_TABLES_BRIDGE, CONFIG_NF_TABLES_IPV4,
CONFIG_NF_TABLES_ARP, CONFIG_NF_TABLES_IPV6, CONFIG_NF_TABLES_NETDEV and
CONFIG_NF_TABLES_INET was merged into the nft_chain_filter.c file which
is now always compiled into the nf_tables.ko file.
This only happened in kernel 4.19 and OpenWrt has to select these as
modules in older kennel versions. Mark them as build-in in the kernel
4.19 specific kernel configuration file which will then not be
overwritten by the package specific settings which try to make them
modular again.

to bool and the code will not be compiled as a own module any more, but
it will be integrated into nf_nat_ipv4.ko or nf_nat_ipv6.ko to save some
memory.
Activate these options as bool in the generic kernel 4.19 configuration
only, to always build them into the nf_nat_ipv*.ko modules. The kmod
file will still try to select them as module, but the generic
configuration will not be overwritten.

The package kmod-ipt-debug builds the module xt_TRACE, which allows
users to use '-j TRACE' as target in the chain PREROUTING of the table
raw in iptables.
The kernel compilation flag NETFILTER_XT_TARGET_TRACE is also enabled so
that this feature which is implemented deep inside the linux IP stack
(for example in sk_buff) is compiled.
But a strace of iptables -t raw -I PREROUTING -p icmp -j TRACE reveals
that an attempt is made to read /usr/lib/iptables/libxt_TRACE.so, which
fails as this dynamic library is not present on the system.
I created the package iptables-mod-trace which takes care of that, and
target TRACE now works!
