Just to make sure I follow you, you are doing this from a clean tree,
right? The config file is only copied to output/build/busybox-*/.config
once (unless you run make busybox-clean-kconfig-for-reconfigure).

It works here:

make savedefconfig

cat defconfig
BR2_aarch64=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_LINARO_AARCH64=y
BR2_INIT_NONE=y
BR2_SYSTEM_BIN_SH_NONE=y
BR2_PACKAGE_BUSYBOX_CONFIG="/tmp/config"
# BR2_TARGET_ROOTFS_TAR is not set

cat /tmp/config
CONFIG_BRCTL=y
# CONFIG_HTTPD is not set

make busybox-dirclean && make busybox-menuconfig
..
[*] brctl (4.7 kb)
[ ] httpd (32 kb)

What Buildroot version are you using?

We already have 'make busybox-update-config' for that:

make busybox-update-config
cp -f /home/peko/source/buildroot/output-busybox/build/busybox-1.33.0/.config /tmp/config
