All tests pass on FreeBSD-8.0-amd64:

clang version 2.9 (trunk 124029)
Target: x86_64-unknown-freebsd8.0
Thread model: posix


# Qemu reports Id = 0x623 as the processor id:
./configure CC=clang --build=core2-unknown-freebsd8.0 --enable-cxx

# The provided libtool exits with an error:
cp /usr/local/bin/libtool .
make
make check


Perhaps this is another Mac OS X specific problem?
