Buildworld failing in /usr/src/gnu/usr.bin/binutils/libbfd

Hello list,

I'm sure I've done something naughty as I've been seeing errors for a
few days, but I've done some troubleshooting and I can't seem to find
the place I shot myself in the foot.  My system is current, and about a
week old right now.  Source was checked out this morning at about 8:30
A.M. EST.  The output of uname -a follows.

FreeBSD current 5.1-CURRENT FreeBSD 5.1-CURRENT #0: Thu Jun  5 10:34:30
EDT 2003     fish_at_current:/usr/obj/usr/src/sys/CURRENT-TWO  i386

Leading up to this build I explicitly ran the following commands.

cd /usr/src
chflags -R noschg /usr/obj/*
rm -rf /usr/obj/*
make cleandir
make cleandir
make buildworld

The tail end of the build error is below.  I have the full build output
if anyone would like to see it.  Repeated builds, even in single-user
mode, all show the same error.  I have tried to ensure that nothing in
/etc/make.conf is biting me, only a few things are defined, primarily
CPUTYPE=i686.  I usually run at CPUTYPE=p3 (as p4 builds broken code
last I heard) but downgraded here to remove a possible source of error. 
CFLAGS and CXXFLAGS are not defined.

Would someone please tell me exactly what stupid thing I'm doing today?

Thanks very much,
