freebsd stable - Nov 2012 - Compilation error while compiling FreeBSD9-STABLE with Clang

Hi.


I got compilation error while compiling FreeBSD9-STABLE with Clang:
   -m32 -c /usr/src/sys/boot/i386/boot2/sio.S
clang: warning: the clang compiler does not support
'-fno-unit-at-a-time'
ld -static -N --gc-sections -nostdlib -m elf_i386_fbsd -Ttext 0x2000 -o
boot2.out /usr/obj/usr/src/sys/boot/i386/boot2/../btx/lib/crt0.o boot2.o
sio.o
objcopy -S -O binary boot2.out boot2.bin
btxld -v -E 0x2000 -f bin -b
/usr/obj/usr/src/sys/boot/i386/boot2/../btx/btx/btx -l boot2.ldr  -o
boot2.ld -P 1 boot2.bin

*** [boot2] Error code 1


And here is my src.conf
CFLAGS+= -O3 -fno-strict-aliasing -pipe -funroll-loops
CXXFLAGS+= -O3 -fno-strict-aliasing -pipe -funroll-loops
COPTFLAGS+= -O3 -pipe -ffast-math -funroll-loops

CC=clang
CXX=clang++
CPP=clang-cpp

WITH_CLANG="YES"
WITH_CLANG_EXTRAS="YES"
WITH_CLANG_IS_CC="YES"

No offense. But why there is no announcement for this issue, at least on
forums.freebsd.org? So people don't waste their time trying to fix the
