Looked at this more.  There isn't any easy solution here, but I guess there are a few options:

1. Add a special mode to LTO where it doesn't require a target machine, and just spits out IR.
2. Force the LLVM default target triple.  But it's not clear we can reliably generate an object file with that.
3. Force the LLVM default target triple, and add a mode to LTO where it doesn't run codegen.
