I know it looks very strange.
Can't you boot a 32bit Ubuntu Live CD? Or install a 32bit Linux in a VM?

First I used make clean linux-x86-native

When I got the error message, I tried to figure out what change could
have caused this by using git blame c3_fmt.c.
To see the error again, I just used make linux-x86-native (without clean).

I should have made this clear in my mail.

I am not even sure whether this is a regression or whether it never
worked. may be I tried -native only for linux-x86-64, and this was my
first attempt with 32bit linux.
