This results in:
-----------------------
target: busybox.prepare
-----------------------

make: invalid option -- '6'
make: invalid option -- '4'
make: invalid option -- '/'
make: invalid option -- '/'
Usage: make [options] [target] ...
Options:
etc.

It seems I have to stick with the bare minimal options I can set
here... Or any other ideas?

Kind regards,

Remy
