Oops, I mean llc, of course. No offend!

Just to push up this question in the list again: Is there any way for 
the humble user of the Windows installer to find out about accepted triples?

I feel this to be necessary to broaden the usage of Clang/LLVM among us 
plain vanilla developers. Usually there is no time to guess and try 
several combinations until one seems to work.
