Just FYI, you would see exact the same problem if you try to compile

As far as I understand this, there is no clang cross-compiler support
at the moment. So compiler generates (somehow) i386 assembler code
which amd64 assembler does not like. Looks like something similar happens
here too...
Have you read http://wiki.freebsd.org/BuildingFreeBSDWithClang, which
suggests to put:
.if !defined(CC) || ${CC} == "cc"
CC=clang
.endif
.if !defined(CXX) || ${CXX} == "c++"
CXX=clang++
.endif
# Don't die on warnings
NO_WERROR=
WERROR=
in your /etc/src.conf (or make.conf, depending on your preference)?
If you use that, it should work, at least for the build32 stage of
buildworld on amd64. This workaround is only needed on amd64, not for
i386.
