Since commit 89e671e3, extboot is broken due to wrong checksum
The problem is that printf "\\$sum" syntax will require an octal
representation, so the fix I'm proposing is to convert it first.
Is there no easy way to tell printf we're on decimal? I don't have a
Linux system handy atm, but I thought \90 was in fact a 90.
Either way, my only complaint would be to introduce a dependency on bc.
