Subject: [PATCH] [libc++] Fix the CMake build on Mac when setting
 MACOSX_DEPLOYMENT_TARGET=10.6

The build file was trying to use LIBCXX_VERSION, which isn't set
anywhere, and also forgot to split the 'compile_flags' list.

Differential Revision: http://reviews.llvm.org/D4860

git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@215463 91177308-0d34-0410-b5e6-96231b3b80d8
