I don't think you need to build & rebuild libcxx. The correct order is:

   1) build libcxxabi
   2) build libcxx
   3) test libcxxabi
   4) test libcxx

This is because of some unfortunate layering violations in libcxxabi, 
where it depends on the c++ library's headers.  Also, the libcxxabi 
tests depend on libcxx being built.


Cheers,
