Simplyfied Kernel Configuration, Full Building Process Results and System Information

Hello, Developers! & Sorry, if I do SomeThing wrong.
Some Time ago, on FreeBSD (at least 11.3 & 12.1 & 12.2) on x86 32-Bit I included ZFS Support into Custom Kernel in following Way:
device	zfs	# in «/usr/src/sys/i386/conf/CrazyBook»
But after DownLoading RelEng/13.0 Sources, This Kernel Configuration does not Build any more. :(
Process of Getting 13.0:
	pkg install gitup
	sed -E -i "" "s~(releng/)([\.\,0-9]*)~\113.0~" "/usr/local/etc/gitup.conf"
	$(whereis -b -q time) -l rm -rf /usr/src/* /usr/src/.[!.]* /usr/obj/* /usr/obj/.[!.]* /usr/ports/* /usr/ports/.[!.]* "/var/db/portsnap" "/var/db/gitup"
	$(whereis -b -q time) -l gitup "release" -v "1" && rm -Rf "/var/db/gitup/release" && for ConfigurationPath in $(find "${Src%"/"}"/sys/*/conf -prune -print); do [ -f "${ConfigurationPath}/GENERIC" ] && printf "\"%s\"\n" "${ConfigurationPath}" && ln -f -s -v ~/Kernels/* "${ConfigurationPath}"; done
First Build the Compiler:
	cd "/usr/src" && script -a -q "/var/tmp/$(date -j "+%Y.%m.%d-%H:%M:%S")-BuildWorld-$(sh -c 'set -o "pipefail" && egrep -i -o "^[[:space:]]*#[[:space:]]*DeFine.*BSD.*Version[[:space:]]+[[:digit:]]+" "/usr/src/sys/sys/param.h" | rev | egrep -o "[[:digit:]]+" | head -n "1" | rev | tr -d "[[:space:]]"' || svnlite info "/usr/src" 2>"/dev/null" | grep --ignore-case -- "RevisiOn" | grep --only-matching "[[:digit:]]\+" || cat "/usr/src/.svnversion" 2>"/dev/null" | tr -d "\r\n" | grep "" || cut -f "2" -d ":" "/usr/src/.gituprevision")-$(( "$(sysctl -n "hw.realmem")" >> 30 ))GB-$(($(sysctl -n "kern.sched.topology_spec" 2>"/dev/null" | grep --extended-regexp --ignore-case --quiet "<Flags>.*Thread.*Group.*</Flags>" >"/dev/null" 2>&1 && printf "$(($(sysctl -n "kern.smp.cpus")/2))" || printf "$(sysctl -n "kern.smp.cpus")")+1))Th.Out" $(whereis -b -q time) -l make buildworld KERNCONF="CrazyBook" -j "$(($(sysctl -n "kern.sched.topology_spec" 2>"/dev/null" | grep --extended-regexp --ignore-case --quiet "<Flags>.*Thread.*Group.*</Flags>" >"/dev/null" 2>&1 && printf "$(($(sysctl -n "kern.smp.cpus")/2))" || printf "$(sysctl -n "kern.smp.cpus")")+1))"	# I understand, the Command looks Ugly, but this is just a Part of Future Script, where Long Expressions will be moved into Functions or AliAces…
To make sure about CLang Parameters, I removed Parameter Files «/etc/src.conf» and «/etc/make.conf»:
	rm -Rf "/etc/src.conf" "/etc/make.conf"
Second try to Build a Custom Kernel:
	cd "/usr/src" && script -a -q "/var/tmp/$(date -j "+%Y.%m.%d-%H:%M:%S")-BuildKernel-$(sh -c 'set -o "pipefail" && egrep -i -o "^[[:space:]]*#[[:space:]]*DeFine.*BSD.*Version[[:space:]]+[[:digit:]]+" "/usr/src/sys/sys/param.h" | rev | egrep -o "[[:digit:]]+" | head -n "1" | rev | tr -d "[[:space:]]"' || svnlite info "/usr/src" 2>"/dev/null" | grep --ignore-case -- "RevisiOn" | grep --only-matching "[[:digit:]]\+" || cat "/usr/src/.svnversion" 2>"/dev/null" | tr -d "\r\n" | grep "" || cut -f "2" -d ":" "/usr/src/.gituprevision")-$(( "$(sysctl -n "hw.realmem")" >> 30 ))GB-$(($(sysctl -n "kern.sched.topology_spec" 2>"/dev/null" | grep --extended-regexp --ignore-case --quiet "<Flags>.*Thread.*Group.*</Flags>" >"/dev/null" 2>&1 && printf "$(($(sysctl -n "kern.smp.cpus")/2))" || printf "$(sysctl -n "kern.smp.cpus")")+1))Th.Out" $(whereis -b -q time) -l make buildkernel KERNCONF="CrazyBook" -j "$(($(sysctl -n "kern.sched.topology_spec" 2>"/dev/null" | grep --extended-regexp --ignore-case --quiet "<Flags>.*Thread.*Group.*</Flags>" >"/dev/null" 2>&1 && printf "$(($(sysctl -n "kern.smp.cpus")/2))" || printf "$(sysctl -n "kern.smp.cpus")")+1))" && printf "\007" && sleep "0.500" && printf "\007" && sleep "1.000" && printf "\007" && sleep "2.000" && printf "\007" && sleep "4.000" && printf "\007"
Now I get Following Error:

When I try to use «options ZFS» instead of «device zfs», or both in kernel Config, I get the same Error.
The very Simplyfied Kernel Configuration, that Produces Described Error is attached to Message. Also attached Full «Make BuildKernel» OutPut (Big File) and Current System «kldstat -v», which shows that Modules «zfs_vdev», «zfs_zvol», «zfsctrl», «zfs», «opensolaris» are in «/boot/kernel/kernel» on 12.1, how to make the same in 13.0?

I saw file «/usr/src/sys/cddl/contrib/opensolaris/common/atomic/i386/opensolaris_atomic.S» in 12.2 Sources, but It was ReMoved in 13.0. I did not try to Copy this File from Previous Distributions, because IMHO this is a «Wrong Way».

Why am I worried about This?
	1. I Read that some Modules (for example, "IPFW", …) work Better (Theoretically, Faster) when they are Embedded into the FreeBSD Kernel, than if they are KLDLoaded during Boot.
	2. SomeTimes (on Some Small-Disk Systems) is useful to make «bzip2 --best --verbose "/boot/kernel/kernel"», but It does not Work on «/boot/kernel/*.ko».
	3. Finally, It worked in Previous Versions of the System — so, Should work in 13.0 too. And the Solution, most likely, is not very Labor-Intensive…

What is the Best Way to Do in Case to Make the Kernel, including «All Needed»? is it safe to use:
	device	zfs
	options	KSTACK_PAGES=4
	makeoptions	WITHOUT_MODULES+="opensolaris zfs"
or better:
	options	ZFS
I did not Find some Detailed Documentation about This Parameters and what is the Difference between «options ZFS» and «device zfs»…
