Here we go (nothing changes):

gandalf@arm-builder:~/busybox-static/bin$ file busybox
busybox: ELF 32-bit LSB executable, ARM, EABI5 version 1 (GNU/Linux), 
statically linked, for GNU/Linux 3.2.0, 
BuildID[sha1]=04ed8120414c0945c115ee4f8551b6bfdc1e9e40, stripped

gandalf@arm-builder:~/busybox-static/bin$ ldd busybox
    not a dynamic executable

gandalf@arm-builder:~/busybox-static/bin$ ./busybox
-bash: ./busybox: cannot execute binary file: Exec format error
