[libcxx][PATCH] Fix for CMakelists.txt

[Michael van der Westhuizen]

The destination directory always exists.  See CMakeLists.txt, line 94 (in the setup_abi_lib macro), where each ABI library directory is created at the time CMake is run.

This patch looks good to me, although it's not necessary for the version of CMake I run (2.8.10.1).  I've tested it against all three ABI libraries on Linux with no regression.
