nit: For a canadian cross, s/(on host)/(on build)/ and s/(on target)/(on host)/.

It's certainly less useful, but since we're going down this path I
wanted to at least raise the question.
GCC prints this info.

Also, I wonder if we shouild print prefix and/or exec_prefix.
We print "(relocatable)" for relocatable directories but I'm left
guessing what the root of the relocatable tree is.
[We also don't explain what "relocatable" means AFAICS.  I know, but I
can imagine a user wondering.]
