This was put in to get libc++ building without libcxxabi. We now have macros that show that we are building against libcxxabi so use that instead. This guards against existing but broken cxxabi.h headers on the system. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@250507 91177308-0d34-0410-b5e6-96231b3b80d8
