I am using OS X 10.9.5 and CMake to build.

It isn't readily apparent how the symbols in the .exp files are chosen
or ordered.  However, adding the following fixed my issue (I can apply
this if y'all deem it to be correct):

diff --git a/lib/libc++abi.exp b/lib/libc++abi.exp
index 87035b2..db965cd 100644
--- a/lib/libc++abi.exp
+++ b/lib/libc++abi.exp
@@ -157,3 +157,10 @@ __ZTIy
 __ZTIx
 __ZTIw

+__ZSt14set_unexpectedPFvvE
+__ZSt15get_new_handlerv
+__ZSt15set_new_handlerPFvvE
+__ZSt9terminatev

Also, maybe I don't understand CMake well enough, but it doesn't
seem like LIBCXX_LIBCPPABI_VERSION is ever populated and that
ABI version 1 will always be chosen.
