ARM64 Linux Kernel Builds but Image Is Not in arch/arm64/boot

I am cross-building the Linux kernel in the Docker container because I want to run BusyBox with the kernel I built myself in qemu as shown in the link below, but there is no kernel image in arch/arm64/boot after the build is finished.
Why?

The Docker container uses archlinux:base-devel.

Build is

export ARCH=arm64
export CROSS_COMPILE=aarch64-linux-gnu-

with

make defconfig
make Image dtbs-j8

You are about to build Linux 6.1.8.

I tried to follow the link, but it didn't work.
Image did not exist

$makeARCH=arm64defconfig
$ make ARCH=arm64CROSS_COMPILE=aarch64-linux-gnu-Image dtbs-j`nproc`

Short answer:

The archlinux:base-devel container image alone does not have enough packages to compile.
The article you are referring to is probably Debian/Ubuntu because you use apt, but you should read the Preparing for Linux for Arm64 section carefully.
The results (error messages) of the command also contain important tips.
You should check it yourself and present it when you ask questions.

Tried steps:

Downloading the kernel source code and make ARCH=arm64defconfig are no major issues.

Running the following command results in an error stating "aarch64-linux-gnu-gcc not found" in the cross compiler:

#makeARCH=arm64CROSS_COMPILE=aarch64-linux-gnu-Image dtbs-j`nproc`
arch/arm64/Makefile:36—Detected assembler with broken.inst;disassembly will be unreliable

make:***[include/config/auto.conf]Deleting file 'include/generated/rustc_cfg' 
make:***[include/config/auto.conf]Deleting file 'include/generated/autoconf.h'

Install additional packages

#pacman-Sarch64-linux-gnu-gcc

If you try to make again, you will not see any errors at first glance, but if you look at ls./arch/arm64/boot/, you will see dtbs, but Image has not been generated.

"This time, when I tried to set the target only to ""Image"" when I made it, I got an error saying ""I couldn't find the bc command."""

#makeARCH=arm64CROSS_COMPILE=aarch64-linux-gnu-Image-j`nproc` 
  CC kernel/bounds.s 
/bin/sh:line1:bc:command not found 
/bin/sh:line1:echo:write error:Broken pipe

  CHKSHA1 include/linux/atomic/atomic-instrumented.h 
make:*** [Makefile:1298:prepare0] Error 2

Install additional packages again.

$pacman-Sbc

We have confirmed that making again after adding the package will also generate an image.

#makeARCH=arm64CROSS_COMPILE=aarch64-linux-gnu-Image-j`nproc`
