[PATCH] [Cmake]

I ran into a problem the other day while running cmake.  I got confused as
to which triple I was actually targeting for a build.  After a bit of
looking and asking questions of a peer, I found that I may not be the only
person having an issue with the cmake output of triple information.  I have
attached a patch which I hope will help to clarify the Host triple being
used for the build and the default triple the build will be targeting.  I
think if we always output the Host triple and the Default Target Triple
(even when they are the same) this will remove any ambiguity.  If this
patch is acceptable, I would appreciate it if someone would commit this
patch for me as I do not have commit privileges myself.  Thanks.
