What makes you think it doesn't work?

make BR2_PACKAGE_BUSYBOX_CONFIG=/tmp/no-such-file busybox-configure
for f in /tmp/no-such-file ; do if [ ! -f "${f}" ]; then printf "Kconfig file or fragment '%s' for '%s' does not exist\n" "${f}" "busybox"; exit 1; fi; done
Kconfig file or fragment '/tmp/no-such-file' for 'busybox' does not exist
make[1]: *** [package/busybox/busybox.mk:409: /tmp/no-such-file] Error 1

echo -e 'CONFIG_BRCTL=y\n# CONFIG_HTTPD is not set' > /tmp/config
make BR2_PACKAGE_BUSYBOX_CONFIG=/tmp/config busybox-configure

make busybox-menuconfig
