-1. `make defconfig`. We set all config as default.
-2. Set static link option in .config: `CONFIG_STATIC=y`. We need a static-linked busybox binary since we does not support dynamic linking now.
-3. Set standalone shell option in .config: `CONFIG_FEATURE_SH_STANDALONE=y`. The standalone ash will try to call busybox applets instead of search binaries in host system. e.g., when running ls, standalone ash will invoke `busybox ls`.
