Stumbled into this on libc++ web page:

clang++ -stdlib=libc++

So yes, you were correct Jacob, I can use default clang on OSX to build
trunk llvm.  Just have to feed this flag to llvm configure and it now
happy.  It must default to libstdc++.

CXXFLAGS='-stdlib=libc++' ../llvm-svn/configure

Looks like llvm trunk is building fine this way.
