<pre>If you use ccache to build libcxx by setting CXX="ccache clang++", check-libcxx
will fail since LIBCXX_COMPILER will be set to "ccache".
We can't just include CMAKE_CXX_COMPILER_ARG1 because of a python parsing
issue, so the best we can do right now is to use CMAKE_CXX_COMPILER_ARG1 if it
exists, and CMAKE_CXX_COMPILER if it doesn't.
