I have no problem using awk as long as the script works with busybox awk.  I 
much prefer that to a dependency on an external tool like perl. :)

Query about the name though: if you're going to tag generated files with a 
beginning underscore, shouldn't all of our generated files have such a tag, 
including things like bb_config.h?
