[PATCH] D41757: [Docs] Add a configuration note about building with CCACHE support.

probinson added a comment.

I know off-list I had suggested not bothering with detailed descriptions of LLVM_CCACHE_SIZE and LLVM_CCACHE_DIR, but now I am not so sure.  If those variables map directly to `ccache` command-line arguments, we should say that here, and people can figure out how to set them by looking at the appropriate help.  If the variables are more complicated, we should add separate entries for them in this doc.
