The FreeBSD LLDB buildbots are ready to go.  (The amd64 buildbot has
been failing due to LLVM test failures since mid December, but LLDB
itself tests fine.  FreeBSD/i386 LLDB doesn't yet work.)

The Debian Clang buildbot claims to use a recent ToT clang, so it
should be fine.

The other Linux buildbot and the Darwin buildbot seem to be broken at
the moment.

In any case, LLDB has already required C++11 for some time.
