The cmake script is failing to copy cxxabi.h to the right place because it was generating to destination path like so /include// and dstdir can legally be blank from my interpretation of the script, and this would then generate a path like libcxx/include// which is illegal. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@178579 91177308-0d34-0410-b5e6-96231b3b80d8
