Hello Galina,

This change transparently disabled ccache on some of my buildbots,
which made them slow (increased build time on
llvm-clang-lld-x86_64-ubuntu-13.04 from 5 minutes to 20 minutes).

I enable ccache by setting CC and CXX environment variables, and these
cmake arguments override my choices.

Dmitri
