Can't make buildworld: very quick error

[Thomas Mueller]

I got a very quick error on "make buildworld" for i386 after success from the same source tree on amd64.

It looked like something with clang, so I checked UPDATING file, no clue for 10-STABLE in contrast to HEAD.

So I look stuck, though I could try to cross-build from just-finished update of FreeBSD 10-STABLE amd64.

Is it some silly little oversight on my part, or is something really awry?

Log file follows:
