building i386 world on amd64 host: failed _at_svn

Dear collegues,

on my builder I have consistent error:

/usr/obj/i386.i386/FreeBSD/pristine/src.current/usr.bin/svn/svn/../lib/libsvn_subr/libsvn_subr.a(named_atomic.o): 
In function `svn_named_atomic__cmpxchg':

*** Error code 1

Stop.
bmake: stopped in /FreeBSD/pristine/src.current/usr.bin/svn/svn
*** Error code 1

host is at contemporary stable/9:

FreeBSD castor.rinet.ru 9.1-STABLE FreeBSD 9.1-STABLE #1 r252026: Thu Jun 20 
15:04:35 MSK 2013     marck_at_castor.rinet.ru:/usr/obj/usr/src/sys/CASTOR  amd64

the build line is

make buildworld __MAKE_CONF=/dev/null TARGET=i386

and no, cleaning /usr/obj/i386.i386 does not help.

On the same time, tinderbox.freebsd.org does not see this.

Any hints?  Thanks!
